Flash has officially ended, so users are finding they must use a workaround with an older version of flash if they want to continue using BioPLAY games. Please see our documentation on how to restore flash.

If you have issues playing videos, we recommend downloading and installing K-Lite Codec Pack. Basic is fine. “Server 1” is usually enough. DO NOT ACCEPT A NEWER VERSION WHEN PROMPTED WHILE INSTALLING K-LITE. K-Lite codec pack should allow you to play any video format in Brain-Trainer software.

Video player grey with no video displayed

If K-Lite is installed and you still see no video displayed in the video window using Video Player, try this workaround:

  1. Open the video player.
  2. Edit play list.
  3. Click “Reload design” (green square at top left).
  4. Now start session.

General issues or bugs

Open Brain-Trainer through C:\Brain-Trainer for BioEra\start_debugger.bat. Perform the steps that created the issue and copy the text in the console window. Send to bt4be for analysis.
