Has your brother in law got his connection working yet. I've setup mine up and as far as I can see its working as far as I've tried 'the game tag question' does his connection get this far. I hope I'm not in for trouble once I've registered. the only problem I had was ZoneAlarm, I've had to down load the Prof edition. I couldn't open the ports on the free version.
Just got to think of a good tag for my son then we should be up and running.
