This has never happened before. Today it happened twice.
So the teams are set and the countdown begins and it kicks me out. It says "A player on this Xbox 360 console is playing on matchmaking. You may not join a matchmaking game in progress."
Then it kicks me to the main menu and says "You have been returned to the main menu because all gamer profiles have been signed out."
Then when I select matchmaking, it has me select a storage device -- My Hard Drive.
Any ideas on what's wrong? Or who can help me with this? ty
