My gamertag is skeetskurt...I seemed to have lost the ability to play Halo 3 matchmaking. I have played the game since it came out. Now, I am no longer linked with my bungie.net profile and everytime I get into a matchmaking game, I get kicked back to the main menu. I have tried two different discs, and my internet is plenty sufficient. Can anyone help me to figure out what the problem is?
