Hello, I have Sims 3 installed and up to date. I am frustrated. I don't know what is going on. I got the Sims3 plus Supernatural and I Origin wouldn't come up. So I uninstalled both and reinstalled Sims3, now Origin works. Now I'm trying to install the Supernatural disk and it says the install Wizard says its downloading and then it asks if I want to completely uninstall Supernatural??? Duh, I'm trying to install it, not uninstall it.What's going on? My Nvidia driver is also up to date.

If you are trying to install it and it's asking to uninstall, means it's already installed. Check the SIMS support forums.
