Hello there, I just bought up Assassin's Creed Brotherhood for my brother yesterday so we could try to play together. Since we're both using a PC to play, we had to make the proper adjustments to the modem ports to allow him to be able to play properly.
But while he can play normally, for some reason whenever I try to join one of his games or that we try to make a game together, it doesn't work and I always get kicked out of the game, and even sometimes sent back into singleplayer mode(wtf).
Anyone know a way to fix that problem? I bought mine from the official sites while the version he got was bought on Steam.
