Hi Obmug.
If that also worked prior to the update, then you best option to getting it fixed again would be to post a file update request.
And if you can, your save game with instructions where it goes.
Please use the update notification system to report a game patch, update or to report that the trainer may not be working with the latest version of the game. If 3 or more reports have been filed, consider BOOSTING the priority of this title for a faster turnaround on the updated trainer.
Hey SmileyJ... The trainer was last updated 12 years ago for the Steam version, and I know there could be some slight problems with the GOG version. I'm just letting others know what works and doesn't work with the trainer for the GOG version.
I also noticed that the command Numpad *: Sniper Cinematic activates but you don't hear it saying, Activated.
