Why Isn't My Sims 3 Launcher Connecting To Origin?

I had bought a new computer and wanted to transfer all my Sims 3 games to it. However, I had bought some in a store (Target/GameStop) and some on Origin. The games from a disk load fine but when I try to "install" my games I bought on Origin, I get this message "Please use The Sims 3 Launcher and update your version of The Sims 3 before installing this product"...When I go to update my Sims 3 Launcher tells me that "Cannot connect to Origin" and it's all up to date. I tried fixing it myself but nothing I do seems to work. Hope you can help me.
