Apparently this game had an update since the last trainer release, the Steam version crashes to desktop when you activate the trainer. I've requested an update, just posting here in case anyone else wants to know.
I guess the same thing has happened and the version needs to be updated.
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.
I did, mine was the first report using that system for this game.
