Hi everyone. I just bought Europe Universalis 4 to a friend, who has a Macintosh, while I have Windows. We tried to start a multiplayer game together, but we realized than while I have the correct checksum (b6eb) for the last version of the game, he has daf8. So I supposed that maybe since he's playing on a mac his checksum is different, not allowing games between these two platforms. Is that correct?
