A freind of mine and I attempted to meet up for a Multiplayer game of ETW. When I would try to join a game hosted by him or him try to join a game hosted by me it wouldn't allow it, saying the games were not compatible. I can join other games without issue, but he cannot. I have the 'gold edition' of the game, where as he got it much further back, but has added the DLC. Any thoughts on this?
