15TrasigaBen Your saves and mods should be intact in the folder you moved, so simply move those folders to the new Sims 3 folder the game has created in Documents > Electronic Arts. Test your mods first in case something in that folder is a problem. Saves are typically fine, or rather a save might not load, but it won't prevent you from loading other saves. They're in the Saves folder, naturally.
Since this thread is a few years old, I'll lock it here. If you need further help, please create your own thread describing the original issue and what happens when you restore the saves and/or mods.
