I don't know how to install an expansion pack in sims 3

I recently bought an expansion pack online, and it gave me the product code, so I went onto the sims 3 website to download the game and it said its already in use, but it told me that its already registered into my account I just have to install it, but I have no idea how to do that...HELP ASAP!!!!

@akcool726  Did you buy the pack from Origin? Does the pack appear in Origin - right click the game icon, click show game details, scroll down and click extra content - look for pack.
