The game was working until 3 days ago when it suddenly doesn't authorise my account. I am unable to access any multiplayer and all my service record and other custom stuff is gone. I have months left on my gold, my internets fine. I've tried uninstalling and reinstalling. I've asked on Facebook, Twitter, halo waypoint but no one has answers. Xbox services didn't help either. I am physically unable to play the game. Can anyone help me to fix the problem?
