So basically i got the code 80151011 when trying to sign in. Freaked out for a little bit and then got on the phone with customer support. I was put through to Chris. Probably the nicest, most down to earth customer support person ever. He ran me through it all in no time. Even had an ol' chat about Defiance and Far Cry 3. It took the pain outta having to do all the deleting and re-downloading. So Shout out to Chris. You're a cool guy. Microsoft you should give this man a raise!
