I have english version of Galactic Civilizations ll and it runs smoothly in my dual core machine. I can copy the serial number that I gave when installed, but using this given serial number GC2-***************** (that was copypasted from front page) gives error and your system says the number is not registered. Well, I am trying to register it, in order to be able to download whatever you have...stuff. In the last page of the manual it says: use this serial number to download exclusive collectors edition content from (XP only)
What should I do to be able to download?
