Same thing is happening to me. Is it a bug?
Can't play multiple games

Just checking, but have you turned on multiplay in your settings (it seems as if you have to do it from within Live)?

Hey chrka. I've looked for a setting like this before but can't find anything. Any idea where I could find it?
I just upgraded my account so I can improve my game but also so that I could play multiple games at once. I want this because of the amount of people who disconnect after playing poorly instead of resigning and making me wait 5 minutes before I can play a new game. However I am unalbe to start any new games once I am in one. I press the "Start New Game" buton but nothing happens. Any ideas?
