Re-install Sims 3 on new computer after old one crashed.
Hello, My computer crashed and I lost all my Sims data. I tried to reinstall with the original discs but when I got to the 20 digit code on the box, it said it was invalid (probably because it belonged to me). I had installed Sims 3, Expansion packs World Adventures, and Ambitions. I recently bought Late Night, but my computer crashed before I downloaded it. How can I reinstall these? Will any of the work I did on each one be restored, or will I need to start in the beginning of each one?
