The Sims 3 Showtime Limited Edition Content not showing up in Game

So, I downloaded Ultimate Venue and Stage, Freestyle DJ Booth and Origin-al Beats 5000 Stereo and then I installed all of the content. The game said that the content is installed successfully, but when I load up the game, none of those items are there. And when I closed the game, I opened the "Installed Content" tab and the items weren't in the list.

Hello,

Try this, please: https://games4theworld.forumotion.com/t2208-sims3pack-installed-world-inaccessible-or-wont-install-fix

Thanks, I will now and reply back to say if it works or not.

//EDIT

Nope, still not there.

They're still not showing up.

You could also try this, if you haven't already. I used this for months on my old computer, and never had a problem. The interface is a little confusing at first, but it's so helpful, especially for organizing all your content.
