I installed the game on my Xbox but I am unable to play it at all. When I first started it up it loaded all the way then I pressed "A" and it said "Downloading additional content" then it would tell me it was unable to. I tried it a few more times, it then started only half-way loading then the game would just close and I'd be back on the Xbox home screen. I just uninstalled and reinstalled it and it's still doing this. I'm frustrated, please help.
