I try to play in multi-player, but after 5-60min the game freeze and write LOST CONNEXION and everyone return to main menu. We are 4 to play and we have try to change the HOST of the game, but we have the same probleme on everyone. We don't lost connexion of the Ventrilo and Steam, only the game lost connexion. The 4 player have the same probleme. We have try to re-install the game, but its change nothing.
