I was playing today and when I stopped to change cars, the game froze. I restarted the xbox and now when the game tries to load my profile it says “It appears your profile has been tampered with. You cannot proceed” and goes back to the home screen. unmodded xbox 360, simply playing single player. I was a level 113 with a good bit of cars sooooooo that’s a pretty big blow. someone please help. please.
