Yeah I have major issue here. Whenever I load Reach, I get signed out of Live and can't sign back in again no matter how many times I try without exiting the game. I put Halo ODST multiplayer disc in and tried that. I managed to get into matchmaking but it kept resetting over and over when it eventually filled the list of players. No live play possible today for me. I hope they sort it.
I should have more faith, it just came back up. Those with headsets were cheering so I guess it wasn't just me.
