So I purchased Dark Avatar, got the serial number and receipt and everything.
I opened up Stardock Central and entered the serial number, whereupon it says I registered successfully, and please close the product registration dialog. I can access the various sections etc etc...
However, when I go to the GalCiv bullet and expand it so that I see Movies, Multimedia, Tutorials, and Dark Avatar (Expansion), the Expansion option still says "Purchase" and won't let me install.
I've tried restarting Stardock Central several times, as well as reinstalling Stardock Central, and I've re-entered my serial number no less than six times.
What should I do?
