Alright so, I was playing on Call of Duty before, around an hour ago. I got bored and decided to play MLB 2k10. It prompted me for an update, I accepted, it failed and returned me to the dashboard. I tried again, same result. So I ignored it and played my player mode. Now, I'm trying to play CoD again, and it too is asking to download an update, failing, and taking me to the dashboard. So as of right now, I can't play any of my disc games (all two of them) on my xbox. I've tried with arcade games, and they work fine. I've cleared my cache multiple times, no help. Any ideas?
