Trainer worked fine up until now. One the game keeps going to windowed mode when I play. In windowed mode, I can activate the trainer but when I go to turn on some trainer options the trainer starts telling me game not found when pressing numpad keys with numlock on as it should be. Even by doing a alt-enter to enter full screen mode in the game, the trainer still complains that there is no game loaded although I am looking directly at the game's menu. I know it's not the best port, but I am a fan of recent (human revolution and the fall) and would like to play if possible. And I loaded the bioshock infinite trainer just to make sure it wasn't something to do with my system and that trainer works perfectly.
