When Playing Halo 3 on an online match, game freezes and I can't do anything. I can push the XBOX guide button and it will make the sound that it usually does but that's it. Then after 10-15 seconds I get the screen where all the players are listed and at the bottom it either says Starting Game or Selecting New Host. When it does finally return to the game, it shows that EVERYONE but me has quit out of the game. Any thoughts on what could be causing this? Or how it would affect my Rank/Experience?
