Alright, every time I start up Gears of War 2 and try to play it, when I get to the screen where you press start to play, my screen turns black and my console freezes. This is only happening to my profile (I've tried a friends and it works fine) and only with Gears of War 2. I've tried deleting and recovering my account, clearing my system cahce, etc. Nothing seems to work. Solution?
