I have 1 version of Trackmania Sunrise, one CD key, which in turn allows me to play Nations. My brother and i want to start a LAN game over the network on Nations, however i can't see his machine, he can see mine, but he can't connect to the game i've set up, and if he sets up a game, i can't see his computer. Is this maybe because we are using the same version of the game? If so, what a load of poo!! I'm hoping it's just a firewall problem we have picked up along the way.
