Error 216 when trying to connect to ANY multiplayer mode!!!

Yep, ditto. For me it worked fine the first day. Was able to play with my another person in my house, who also has a license for the game. The next day we could never join up in a multi-player game. I would always get the error 216 and get kicked out. I could leave the group and play multi-player on my own though. I only saw the error when trying to play in a group.
