The One Domo gave you must of been faulty, nothing you can do now really. You can just try finding a new CD Key I guess, good luck.

I got the same problems, I can play in LAN only. But maybe the problem is in that the game and the CDKey are not original. (Downloaded form a Torrent Tracker, LOL).

yeah i think the CD key i gave you was a faulty internet one, i can find you a working one. I'll can you both a working CD key. (some of them half work lol)

k cool just pm it

Good luck..
