Captconan is right. I had to redo my computer when it had the virus, and I wasn't aware that I had to have all of my information when reinstalling Spore. Now I have only my most recent creations on my game.

Reinstall any expansion packs you have too, or the game will crash. (Does not apply to robot parts pack)

Then you need to copy the spore folder from %appdata%, copy both of those to the other computer, then reinstall spore.

I did this myslef once, when my computer got a virus. You need to copy a spore folder (I forget the name) from your documents folder.
