os windows 7 64bit mcafee anti virus sure i let the trainer authenticate because i dunno how not letting that trainer authenticate
Ok firstly Turn off your Security programs. Secondly start the trainer and steam in Admin mode. Wait for it to authenticate about two or three seconds Do not open anything or click on any other screen until its done. It will say if its still authenticating at the bottom of the trainer. Then start the game.
If the trainer crashes when its authenticating. You will have to make sure you revert IE back to IE 9. If none of that works you might have a mod that is interfering with the trainer.
