I just downloaded the latest update and attempted to play a Halo: CE campaign. The map wouldn’t even load. Then I went into H2:A Rumble. It took about 5 minutes to find enough people, and then when the map started to load the game froze and kicked me to the dashboard.
The kick-to-dashboard problem has been ongoing since Sunday and is only when I’m online. My wife and I played the H2:A campaign all day today offline no problem. Soon as I connect to Live, though, it crashes every time.
