I was trying to play online with a friend, however it did not work. I did not seem to have any trouble a week ago playing online. My game is up-to-date (updated on March 10). When I hovered my mouse over his server, it said the host had a different version than mine.He has Empire: Total War the special edition, and I don't I wasn't able to join any other games (all their writing was in red and I gave me the same message). He wasn't able to join my game i created either. What could it be? I'm hoping it doesn't matter if you have the special edition, because I can't find it anywhere where I can buy it separately.
