No no, I didnt know that you have to email support, to get cdkey, because support page was saying something different
"To establish a network multiplayer game between two or more players, different CD-keys are needed for each player. Currently we're unable to distribute those keys through our web site, but we're working on solving that issue, and unique keys will be available for each customer soon."
They should change that to "contact us if you want cdkey" ;)
Now im waiting for my cdkey, so I can start playing game online. I wonder, how many people are currently playing MP?
