Rise of Legends Networking problems

turns out it was stupid McAfee that was causing the problem. Hamachi works like a dream.

McAfee sucks bad

Hey!

We are 4 guys here at my LAN party. But we only have this problem with one guy. We can´t join his games and he can´t join any game at all.
However the rest of us can play without any problems.

The "problem child" has also installed McAfee, but he says that this won´t be the problem, because he had disabled the firewall.

Is this enough or could there be other problems?

Do you guys all have the same OS?
Because 3 of us(where everything works fine) have WinXP Home/Pro SP1 and the 4th who can´t join or host has WinXP Pro SP2.
Might that be the problem?
