kyeballer22​  Please open Keychain Access, in Applications > Utilities.  Search for sims3 and delete any entries you see.  If you have a new Sims 3 folder in Documents > Electronic Arts, move or rename it.  Then try to sign into the Store site and see whether you can download any content.  Don't sign into the launcher.

If you can't download the Store content, please post a screenshot of what happens when you try.
