Reinstalling

I've recently found several sites that I adore, the lots and sims are amazing but I realized I can't download them into my game because I forgot to download clean installer at the beginning, so after I downloaded several thousands of cc and downloaded the clean installer afterwards... I couldn't download any sims and lots. So last night I decided to uninstall all of my games, I haven't reinstalled them yet because of school, but I can't wait until I get all of my cc back.
