For the past two days I have been unable to play any multiplayer games on Halo 4. Whenever I tried, it would load in incoming players, allow me to select a map, and then right as the last beep goes off to start the UNSC eagle loading screen I get bumped back to the lobby. When I joined my friends' party, they all continued onto the match while i was sent back. At the bottom of the screen it says that everyone left the party but when asked they said that I was the only one who left. I've already checked my connection multiple times, reset the wireless settings, as well as restarted the modem and router. The thought that I've wasted my money is not making this any easier so any help would be appreciated.
