After I bought the ambitions expansion pack my Sims 3 will not open. I have bought other expansion packs that work just fine; any ideas how I get can this to work? Whenever I try to open Sims 3 I get an error message. I am also not eligible for a return on this game, so if I could get it to work that would be great.
There is a sticky on this Mac forum with instructions on how to resolve the issue - http://answers.ea.com/t5/The-Sims-Mac/CURRENT-ISSUE-Unknown-Error-issue-in-Sims-3-in-El-Capitan-Sier...
Using CC/Mods is at your own risk, EA are not responsible for making the game compatible with 3rd party content, the creator is.
