I have this error code as well but for a different reason. I was about to play Battlefield 3 online and before i manage to get to a lobby, it said that my account has been disabled due to my billing information is no longer valid, and it asks me to update it or add a new method. and theres nothing wrong with it. the card im using dont expire until 2013 and it has worked well until last night. i tried updating it but it just says that theres an error with Xbox Live Market place try again later. and i did and it still pops up with the same message. its starting to get under my skin.
