Can't get multiplayer working between two Windows 7 Home Premium machines. I have firewall permission to both machines. Any suggestions? TIA! Steve Further to that, on one machine I can set up a multiplayer game, but on the other one, ID crashes every time I try to set up a multiplayer game.
Also I have installed the Widescreen mod, Tweaks, Item Update and Unfinished biz mods to both machines - the one that crashes and the one that doesn't when you try to start multiplayer.
