Well I got live, and I played some games. Halo 3 worked perfectly, but then I got on to Cod4. I recieved the update, but then when I proceeded to press multiplayer got a black screen and the game froze. So I tried the campaign game. I did the first level then tried multiplayer again, and it works. Until the end of the match that is when it freezes. So then I try again, and this time I cannot get to the multiplayer menu again and get the black screen. Then I try the first level of campaign again and it works, until the match starts, then it freezes. The next time I get halfway through a match before it froze. I am stumped anyone know what to do?
