Answer from Steam support today: "We are investigating this issue further. As soon as we have more information, we will update your ticket. "
Nice hint rcl_damsku. But I don't have windows. Maybe I have to buy Windows 7 license (over 100 euros), just to get one CD key from Steam
I have waited 10 days now fix for this problem. I sent my first message about this problem to Steam support 29.5. Maybe I have to wait 10 days more, or maybe 20 days more. Who knows.
I have waited 8 days now answer from Paradox Interactive support (http://paradox.zendesk.com/)... but nothing... Nice support service!! I am gonna use this service more often!!![]()
You could try using boot camp, then install steam and activate CiM through there.
Or go to your friend's house, log in with your account, get the CD key, and go back home...
