i have the same problem too and i dont know hotw to use it ................... oh well

(1.) Set a static Ip on your Computers
Google- "How to set static Ip on windows xp"

(2.) Google Portsforward Crusader and follow directions on forwrding any ports needed to
your computer,

(3.) Open nessasary ports on windows Firewall. allowing exceptions for teh needed ports.
also make an exception for teh game it's self on windows firewall

(4.) download Gamespy Arcade and update to version 2.0

(5.) Due to a lot of telephone dsl services you may not be able to host online games for
anyone but those inside your home or on your own network. But now you dont even start the
game just start gamespy and go to Crusader, then main lobby, and click create game and
once other person sees teh game yeou are hosting appear they can join the game and you
click launch game after everyone has clicked ready.
