You sent 5 messsages in 2 days? Perhaps thats the reason you didn't get a CD Key yet.
They said they try to reply to every request within two business days..
While i don't know wether they work on saturdays in Poland and/or at GOG, most people i know, wether in Europe or not do only work from Monday-Friday. Even if they do,it's 6 in the morning for them (and me too, i should have gone to bed long ago..but you know..)
So if you didn't buy it Thurdsay morning (for them..) they didn't have two business days.
Also many people finish work earlier on fridays etc..
Making even more threads just keeps them from doing their work.
Just be patient, and check your mails.

Aurion has it, just use a little patience.
If you like, you can play in Single Player mode now and export your character over to an "Open Multiplayer" game later when you have the keys.

Ok thanks you all :):)i patient for my cd key and i play solo for export when i get it thanks

Did you get your cd keys yet? Please update us.
Other than contacting support the rest of what you have to do is wait to get your keys, then once you get them you should be good to go.
Just make an account to log in online, enter your keys, and you should be ready to play MP.
