am i the only one whos game locks up. i have the xbox us version and as soon as i hit start it checks data then freezes. I checked my game data and there are no corrupted files!. i dont know whats going on man

I don't know what's going on either, man.

Try creating a new profile on your Xbox (it doesn't have to be an Xbox Live enabled profile). I am not saying it will work, but I am curious if the problem is associated with the profile or something else. 
 
Do you have any DLC?

it was the save file, i moved the current one to a usb stick and ran the game without the stick in and it worked. i tried again with the stick with the save file on it and it locked up so i just deleted it and started over. thanks though guys
