Okay, I downloaded the game from Steam, installed Framework 3.5, ran the trainer as an Admin, pressed F1 at the main menu, activated the options I wanted to use, and the game crashes when I try to play.
*Oh, and I'm running Windows 7 with no antivirus turned on.
I'm having a similar problem. I start up the trainer(no problem). I start the game(no problem). when I press f1 I can hear trainer activated so it seems to work, however as soon as I try to start a mission or a campaing the games crashes. I have the latest version of the game via steam and the latest version of the. the game has been updated a few days ago. could this be the problem and if so will the trainer be updated?
