My friend's Xbox 360 is constantly updating no matter what game it's doing. It could be a disk game or a arcade game, it just says it needs to update. The problem is, every game needed this on the same exact day, and everytime he tries, he keeps getting a message saying he can't connect to the server to do download the update. Yet, at the same time, I can still talk to him on xbox and he can access the market place, so it's not a problem with his connection. What is the problem?
