i am trying to play WC3 on LAN with my friends. they all use macbook. i use macpro. one of us created a game. everyone elses saw it and clicked "Join game" however, it wouldnt work. it doesn't freeze, but it wouldn't join. after awhile, we got an error saying "Unable to join the game. try another one" we took turn to create game, changed map, resetup the network ... but all this didnt work either. any idea?
