Ok, so i just got the new xbox 360 arcade version, and im using that with my old harddrive. I put in gow 2 and it said there was a new update, so i downloaded it, and now everytime i start up gow 2 it freezes my xbox. I cleared the cache, then it doesnt freeze anymore but i cant play on XBL. Any ideas on how to fix it? It also does this with rock band 2, it seems like any new updates for games freeze my xbox.
