Just a couple weeks ago I purchased Assassins Creed Brotherhood for about $6 on the marketplace. It was on sale and I had $10 on my account so I bought it. I downloaded it over night and tried to play but when I did it would either tell me "the disc is
unreadable" on startup, or when I started up my save game (which really wasnt a save because I didn't get to play at all.) I tried redownloading it multiple times clearing cache and everything. Then when I tried to start it it would freeze my xbox. So I cleared
my system cache again and redownloaded it and now when i try to start it it just says "The game couldn't start. Try downloading the game again" I also just recently purchased portal 2 and crysis 3 on demand and had similar problems. Portal 2 seems to work
now but crysis 3 and ac brotherhood are still giving me errors. Also the games I had previously downloaded work just fine. I really hope its not my hard drive I dont have money for a new one right now. Any help would be appreciated.
