Did you download the proper trainer as there is either one for the STEAM and one for the GOG version of the game?

As you already did file a report I'll leave this here for others ...
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.
