Hi @CandyCornCC
Make sure you are using the right path Spore folder Spore" located in:
...\AppData\Roaming\SPORE
The most important data is in the main folder "Games"
There are two "saves" Game0 and Game0.old folders (they are your home planet)
Keep an eye to " Pollination.package ", because there all your (downloaded) creations and Sporepedia are located.
Backup the entire Spore folder and drag it to the desktop Launch the game again.
The main folder should recreate again.
Move each individual file from the Spore desktop folder to the new Spore folder in AppData path.
Please do not take (copy) the entire folder and replace it.
Hope you understand what i mean?
