hy all...i still have the demo version and i started a dedicated server not from game..with the program downloaded from additional downloads..i first had a problem with the port but i changed it and works....now when my brother tries to connect in the server windows appears COULD NOT SET TCP_NODELAY...i use vista and he uses xp...he have to use same port as me when connecting with "join specific server"..i don't think it counts that i have a dynamic ip adress
