Have you registered on the
War Control Panel?You need to register in the WCP (War control panel) to be able to log in.
When logged in you can create battalions connected to a RELIC nick (CaSe SeSsItIvE), fill your battalion with units and play.
(using the vids etc in the launcher is handy)
PS: I would suggest getting
Ventrilo, it is an VoIP (so basicly you talk with a mic over the internet, Bit like teamspeak)
You need a password to be able to connect to our ventrilo server though (the server adress is ventrilo.europeinruins.com) the password is sp4m
You can also use chat here however if you have no mic, and listening can be very handy for your teammates.
It's also the best place for help on making good companies, getting your game to work etc.
