Release Notes for EEGer4 440x (October 2022)
EEGer4 440x has been released with a variety of new features and bug fixes, as well as backend improvements to the software and its development
process. This release will act as a stable foundation for future development to occur from, allowing improvements to be made more quickly.
New Features These are key changes made in this version intended to expand EEGer’s functionality, make the software easier to use, or to implement
requested features.
Improved presentation of Main Screen, Wave Screen, and various submenus by adding a new background image, adjusting the default color
scheme, and adjusting the fonts.
Adjusted Top Navigation Bar to separate Help into Support and Info menus.
Added support for improved visibility of rewards (Configurable: Options>EEGer Configuration Options>Preference>15 Set over threshold line
Added tech support upload utility (Support>Upload Tech Support Information) to help with critical failure diagnosis and error code reporting.
Added support for BEEMedic NeuroAmp devices.
Updated warning message interface to be less intrusive (click to see warning messages).
Added ability to view EEG Store’s Knowledge Base Articles (KBAs) from within EEGer (Support>Knowledge Base Articles).
Home Use Client Files (EKC, EKR) downloaded from HU Cloud now automatically install when leaving the menu.
Changed display of feedback displays (games) to include all initialized games, and to specify which games require an external monitor.
Updated software End User License Agreement (EULA).
Removed deprecated buttons related to Home Use, as well as some deprecated options.
Renewal date of the currently installed keyfile will be displayed in the bottom left of EEGer’s Main Screen for all subscription types.
Removed Single Monitor Warning when opening EEGer in Dual Monitor mode without an external display connected.
Bug Fixes This is a selection of errors resolved with this release, as well as improvements made to existing features to bring them in line with our
original intentions. While issues are encountered and resolved during development, we thank all users who take time to report problems or provide
suggestions, many of which have been addressed by this release.
Clinical Override now correctly enables live session controls in addition to the ability to change the Plan Session screen.
Added new communication dll to handle longer gamedef option names.
Resolved a crash related to FullRecord license enable while using the Q20/Q21 acquisition devices.
Corrected feedback display issue when switching from 8-trace Dual to SingleA/SingleB with some games.
Resolved an issue which could cause incorrect layouts to appear when creating multiple Home Use Client Files.
Adjusted EEGer main screen to rebuild more often to stay updated with changes to the license and selected Client ID.
Updated GetKeyfiles utility to only install keyfiles if a new key or change is available on the server.
Adjusted button sizes to be better when using 4k displays.
Fixed an error preventing Plan Session screen from saving after canceling the selection of a Custom Session Plan.

EEGer4 Software Changelog
Fixed an error involving Filter Presets not saving or crashing while editing.
Reduced disruptive screen flashing throughout the software during loading, made more apparent by updated color scheme.
Adjusted sorting of HU Cloud so that newer files are easier to locate when many files are uploaded (it is still recommended for the
Supervising Clinician to delete files once they have been installed).
Fixed issue causing black screens to appear after running some games in some display configurations.
Adjusted logic to properly display Keyfile Information when installing files via GetKeyfiles.
Corrected an error that caused default serial number and passkey for BrainMaster devices to be displayed.
Reduced repetitive warning message popups in certain conditions.
Unresolved Issues These are issues that have been observed in the software or reported by users, but are not resolved by this software update. Work
will continue to address these issues in upcoming releases of the software. Users who are impacted are encouraged to contact technical support for
possible workarounds, to provide additional information from their systems, and to be notified when these issues are resolved.
AutoAmp utility reports TT-USB devices as ProSB and requires user configuration.
AutoAmp utility can fail to identify the correct amplifier if multiple amplifiers are connected at the same time.
AutoAmp utility can fail to assign the correct COM Port when using Wiz devices if the COM Port changes.
Crashing may be observed when opening the software if a Wiz device is configured and the amplifier is not connected to the computer.
Crashing may be observed when exiting a session if a Wiz device is configured and the amplifier is not connected to the computer.
Crashing may be observed when starting EEGer with a ProSB or TTUSB adapter connected if AutoAmp is enabled. To avoid this issue, leave the
amplifier’s cable disconnected from the computer when first opening the software and manually configure the device, turning off AutoAmp.
Note: Disabling AutoAmp utility once the device has been properly configured (during first-time startup or after manually configuring the
device) will avoid these issues. AutoAmp utility can be disabled at Options>EEGer Configuration Options>Specials>9 Check device once at
During live training, EEGer is unable to display Optima impedance readings until the software completes its initializing process. Users must
wait until EEGer completes initializing (signal observed on RAW trace) before checking impedance.
GetKeyfiles utility may download an expired keyfile enable if no keyfile has been installed locally.
ELS and ELP files cannot be downloaded in Clinical Mode unless in Force HU Mode.
Dongle Groups have not been fully implemented at this time.
The default Feedback Mode for SMR 8p reports an unlicensed error message, resolved by changing to a different feedback mode.
Space Race & other additional games may display incorrectly in some configurations while using a 4k monitor. Adjusting the display to
1920x1080p before opening EEGer allows these games to function as intended.
Client Info Box on EEGer’s Main Screen may not update in certain conditions, resolved by exiting popup menus or reselecting the Client ID.
Feedback Displays (games) may not take screen focus in all conditions when using Dual Monitor mode and other windows are open on the
computer. This is resolved by selecting the game on the Windows Taskbar or selecting the game using alt+tab shortcut.
When checking impedance with Wiz devices, the message ‘See amp for impedance’ may appear if an open connection is detected.

EEGer4 Software Changelog
DVDGame 1.55 does not achieve 0% video quality in White or Black Overlay. It is recommended to set a higher minimum floor to avoid visual
Discovery amplifiers may not connect to EEGer in certain conditions, and display incorrect error messages depending upon configuration.
The Wave Screen may appear to move ‘slower’ when viewed at higher resolutions, such as on 4k displays. This does not impact feedback.
Discrete reward feedback can become delayed when using DVDGame at maximum reward with minimum time between reward events.
Performing multiple backups to the same directory within the same day produces an error message. This is resolved by removing the
existing backup folders, choosing a different directory, or waiting to backup on another day.
Unarchiving clients can result in errors in some conditions.
