Can anyone tell me PLEASE PLEASE how you get a multiplayer game set up, i can never make it work, the request server button doesn't work, when i type the ip address manually it says joing game but never does!!! Please Help

Make sure it's the right port, and also make sure you have LAN selected down the bottom.

i do, and i host it in a DMZ zone as well, occasionally i do get it going but it happens for no apparent reasons and then it freezez but more often than not it just doesn't show anything
