World's not working after downloading on Sims 4

Hey HeatherD270​, 

It sounds like there might've been an issue with your install.

Please try the following steps to troubleshoot this:

1. Quit EA App and make sure the EA background services are closed in Task Manager
2. Delete the main folders for your packs in the install location (should be EP01, EP06, and EP08)
   The packs should be located in the same folder as your base game. If they're located in a folders within Documents, then it isn't installed in the right location.
3. Open EA App and reinstall those packs one at a time. Wait until it says 'Installation complete' before moving on
4. Start Sims 4 and check if the worlds are available

Let us know how it goes, thanks! 

Hello. I have the same issue as the OP and I just tried what you said, and it didn't work. I bought and downloaded Adventure Awaits today but I cannot open the world or access anything from the pack even after all the trouble shooting. I deleted the folder EP20 and redownloaded. Still not working. I repaired my game too. 

Hey, you have to activate your new packs on the marketplace! I found this solution on another thread. Go to the marketplace and then my collection and then select the deactivated packs and it will ask you to restart the game and then those packs should work! My new one did! 

Hey simalicious357​, 

Since you've already tried reinstalling and repairing the game to no avail, please try clearing the EA App's cache before repeating those steps again. Sometimes, the cache keeps old install data, which can interfere with the reinstallation. 

Also, do double-check that the EP20 folder is in the same location as the base game, and wait until the install is complete before launching your game. Thanks! 

Thank you so much ,you’re a lifesaver 🙏🏻

every time I try to activate my deactivated packs, my other packs deactivate, and the other ones that were deactivated become activated. I’ve tried selecting the deactivated packs individually, but whenever I hit continue my other packs deactivate. 

Also have the same issue after I installed university, vampires, and get famous packs. Neither of the worlds will allow me access. 

You have to select all of them to activate then. 

THANK YOU THIS WAS THE SOLUTION!!!

How do you activate it?? Its not showing up as an option in marketplace when I click the game.
