so i decided i wanted to install and play The Sims 3, and downloaded three expansion packs, Late Night, High-End Loft, Pets, and the original game.
I first downloaded The "Base Game"
Then the other 3.
So... it worked fine with the Pets... and i've used it ever sense.
Today i decided to change it up a little.
I decided i wanted to play the Late Night Expansion Pack instead so i could try it out.
I put the disk in, and waited for the 'Auto Run' to pop up. It popped up, i clicked it, it went away. i tried to click play on Origin, like i do with Pets. It didnt work. A bar popped up and said: "Unable to start process. Please put in the Sims 3 Pets Expansion Pack."
I really want to play the Late Night expansion pack, but it wont let me...
HELP PLEASE
Thank you.

@JAB041604 all the games work together. They add onto the base game.
So you'll notice even if you play with the Pets disc, you will be able to select Bridgeport as a new town (it's the town that came with Late Night). Similarly, you could have a vampire (Late Night) that marries an alien (Seasons), lives in Twinbrook (Ambitions) and has a dog (Pets).
Does that make sense?
