Re: Registering A Game
@michelle_renee86 There should be a way, yes, although I'm not totally sure whether the "normal" way works. If it doesn't, let me know, and I'll ask if there's something else you should do instead.
Open your Origin game library, right-click on the Sims 3 icon, and select Game Properties. Among other things, you should see a 20-character CD key. Try using that key to register on the exchange site; you can copy and paste it to make sure the code is entered correctly.
