It's not clear what you're trying to register, but I'll assume that it's GalCiv2. I'll also assume that you're trying to add a character to the metaverse. Please verify with us what you're trying to do and we might be able to help. Being the weekend, you might not hear back from Stardock very soon.
If you're trying to get on the metaverse as I'm assuming, you'll need to register your game through Impulse first.
To make sure you have the game registered in Impulse, open Impulse and click the My Games tab. The games you bought should be listed there.
There could be a number of different situations, depending on what the My Games tab shows. It could say Installed, Available or nothing at all.
Make a mental note of what it shows.
Regardless of what you noted, click the blue planet icon on the upper left side of the screen. That'll bring up a menu. On that menu, click on Register a product. That'll pop up another screen.
In that screen, there should be a registration code for Galactic Civilizations II. There might be more registrations, but that's the one you're looking for. Copy that code.
If that code wasn't there, click on the Add Registration button on the bottom right-ish of the screen and enter your information there.
Once done, you can use that code to register a character in the Metaverse.
Let us know how this part went and we can continue from there if need be. When you reply, let us know what your My Games tab said. Don't post your serial numbers though.
