The Sims 3 on Steam - Supernatural on Origin - what can I do?

When I try to type in my game codes in Origin it doesn't recognize them.

Hm

Then I would contact Customer Support.

They can be found here: https://help.ea.com/contact-us

You have the option to contact them by mail, phone or Live Chat. Make sure you have a game, a category and a platform selected for the options to become available.

For Live Chat, make sure to choose US as your country.

You have to register the codes from steam on www.thesims3.com and then they'll show up on your origin account associated with your sims3 account.

Actually, my codes ar all registered on TheSims3.com -- I have the badges to prove it! -- and its a no go, I had to fill out a support ticket.  For some reason EA not only feels that after its customers have invested in the Steam version that we have to uninstall and move over to Origin in order to play supernatural, but in addition they have invalidated my original codes, making doing so a nightmare.  This is deeply disappointing and unnessessary that in order to play our games we have to go through a support ticket just to be able to activate games we already own again. . . but that indeed is your answer.
