How do I retrieve my old Spore creations after installing Windows 7?

After I installed windows 7 I dragged and dropped all my creations from windows.old to my current document. When I play the game none of them are there. Could it be from not having the Creepy and Cute expansion pack?How do I retrieve my old Spore creations after installing Windows 7?
Go to the Sporepedia, and look for your desired creations. Right-click the small PNG images, and save it into an easy-to-find place, such as your desktop. Now, when you have your PNGs, you can either copy and paste them into the correct folders in "My Spore Creations", eg. Add a creature into the "Creatures" folder. Or, a personal favorite, open up Spore or Galactic Adventures in windowed mode (you can do this easily by pressing Alt+Enter) and simply drag and drop the PNG images into your game. The creations shall be downloaded instantly!
