Running steam retail edition legitimately purchased, starting trainer 12.0.2.33515 first on win 7 64 bit in admin mode with XPSP3 compatibility. then starting game and pressing F1 at main menu, I hear the trainer activated prompt. As soon as I load my game, my browser opens and says they have detected I'm running a pirated version of the game which I'm not.
Aye, I couldn't say it better myself. This is really weird. 1 and 2 are fine but not 3
