Just dropping in to give this thread a little revive. Husband and I were a little trigger happy and purchased two copies of this game before doing any proper research. To be clear, we bought this game specifically for the multiplayer aspect.

I've gone over this entire thread and tried every little thing that's been suggested, we're still getting that dreaded error message. From speaking with support, I understand that the patch is currently being routed through the powers that be at MS, so here's to hoping.

As it stands now, if you haven't purchased the game, I suggest you WAIT (!!!!) until the kinks have been ironed out.
