Re: Sims 3 store content disappeared
@BobLazarELE115 I've split your post into its own thread in the Sims 3 section, since the other thread is about Sims 4.
Please move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop. Open the launcher to create a clean folder, download one store item, install it, and see whether it appears in-game. If it does, quit, restart your computer, and check again, just to make sure. If it's still there, you can install the rest of your store content in small batches, no more than about six items at a time. Worlds are large files and should be handled separately, not in a batch with anything else
It's also a good idea to test the store content periodically to make sure it hasn't disappeared. When you confirm that everything so far is installed properly, you can make a backup copy of that Sims 3 folder; if your store stuff disappears later, it's easy to trash the newest Sims 3 folder and restore the most recent backup.
If your store content disappears at any point, please tell me when it happens, and let me know whether your computer runs Windows or macOS.
