Got a friend that we play Barb and Africa corp all the time multi player. He up graded to WIN7, now he cannot host or join. he gets a 'cannot connect to tcp/ip network. We shut off firewalls, everything the same, cable modem, etc except for his new rig. Opened up all the ports, must be a win 7 setting I don't know about( I still run XP). When I host, he cannot connect either..
