I having trouble registering the sn to my account. I get the error saying sn not registered to this account. I have a us copy bought from walmart (the collector's edition). I was able to download the first update but have not been able to download the lastest. I did have troubles creating an account here and it took several tries to do it. Just so you know I do not use stardock central, and the computer I play gc2 on is not online so I usualy download updates to my usb key and transfer them to my computer with gc2. any help fixing my account would be great as this is a enjoyable game and I would like to play it more.
