Can any one help me to set up a home LAN connection between my two computers so that my son and I can play a Personally modded version of Automobilista (it is independant from my purchased copy). I have set up a IP address and I can copy files from one computer to the other but when I attempt to play a multi player game, computer 1 freezes. Is it because the game has been modded? I have made a version of Aussie Touring Car Masters from rFactor
