Check the other topics in this forum, I don't remember where exactly but Castellon stated somewhere that the cd-keys that where given were actually an error and that everyone else will get theirs on release day.

Well, it's f****d up and unfair... Steam and/or Paradox could do a better job. I mean, they could either correct the bug (bug is still there, given which day 17blue17 pre-ordered) or give the cd-keys to everybody.
As it is, the situation is messy, and, dare i say, not very professional regarding both Steam and Paradox.
