My problem wasn't the disc that wouldn't work.
I bought the disc, it installed perfectly, but recently, because I have other (older) expansions and the discs were getting weary, I switched to playing via Origin.
So all my downloads wouldn't install properly.
Here's the solution to it and it's super simple:
You just go to your account on the Sims3 website and go to your purchases and then you just download the * again from scratch.
It just needs a new download I guess.
Then it works! :D

I've been having the same problem. Every time I go into the launcher it asks for a code, and the bundle didn't come with a code so I'm trying to look up the code, but everyone is telling me to go to a website and none of them tell me anything. PLEASE HELP I'm desperate.
