The preview update currently being tested has bug whereas a few user have trouble testing (accessing) their multiplayer connection. I honestly think that this bug affects those peoples abilities to connect with the "Partner Services" and hence makes the game unplayable for us who suffer from this. I've done UDP/TCP port forwarding as reccommended by both bungie and microsoft (all ports suggested), ive restated my router, connected via ethernet, uninstalled/reinstalled the game, checked that NAT is open and everything else that has been suggested. The preview update is the only thing left in my mind which could be the problem. I downloaded it last night (after having my game interrupted thanks a lot microsoft) and today i can't play the game. P.S If anyone knows how to rollback to a stable Xbox OS version Please tell me! P.P.S. Link to Album of my two error messages, 1 for multiplayer connection and the other is the cattle error i get.
