Lost Serial Code

As I said before, the registry code listed for my base game is the code for World Adventures NOT the base game. I need the code for my base game. 

I would contact EA about that: http://eahelp.ea.com/en/ . For help with navigating the site, see this: http://sims3.crinrict.com/en/2012/10/how-to-contact-ea.html

then contact EA if they put the same code on your base game and world adventures

I found a program that ran a registry on my computer and listed all the codes for all of my sims games by going through the files on my computer. I confirmed my other games so I believe it is trusted. Don't understand why it is wrong on Origin though. Thank you all for your imput.
