sims expansions issues

Well i decided to download the sims again... The ones i purchased my self a while ago i downloaded through origin but i also wanted the ones i didnt buy like Generations, Seasons, Pets, and University Life. I downloaded each of them and installed following the installation guide. Then i aplied the Ultimate Fix. When i go into the launcher at the bottom it says those games are installed but when i go into the actual game none of the worlds are available to me. Why is this? is there anyone who is able to help me... I will also download Team Viewer if you need that to help me

So basically, you can't launch Appaloosa Plains, right?

correct, i only get the worlds from the games that i purchased and downloaded from origin

So the only problem is Pets?
If you open a new game, do you get content from the expansions?

I got none of the content... But i re downloaded everything and it seems i must have messed up a step the first time because they seem to be working now... but once the new Island Paradise expansion comes out what will i need to do so the games continue to work?

Don't worry, by then when the update comes out the team will come out with an updated Ultimate Fix
