How to get Katy Perry content and Limited Edition University Life content on new computer

Hello!

I recently bought a new computer to play the Sims 3 games on and I downloaded everything perfectly and all of my games are updated. But I bought the Showtime Katy Perry Collector's Edition and the Limited Edition University Life EPs on Origin. Most of my games I have bought through Orgin. I bought both games in March of last year.  But when I go into the actual game there is no Katy Perry content or any of the Limited Edition content that came with UL. I just want to know how to get the content onto my new computer. I still have my old computer and all of the games still installed on it if that helps.

Thanks in advance!
