So currently I downloaded The Sims 3 based game and some expansion packs straight from Origin and haven't registered the sims 3's online account. any ways to link the origin's account to the sims 3 website, so that I can download the exchange?
you log into the sims 3 account with the same email and password as you used on origin this ties the accounts together
edit to add Purchasing The Sims 3, expansion packs, and stuff packs in the Origin Store will auto-register the game to your Origin Account
Note, you do not need to re-register your game at TheSims3.com. New users to TheSims3.com, however, will have to complete an account registration process
