I bought a Sims expansion for my BF but didn't know he owns all the Sims 3 stuff off Origin. How do we get the CD Key from the expansion I sent him to activate on Origin? He already accepted the gift and it shows in his gift inventory but Steam won't put it in his library because he doesn't own the base game on Steam.
edit: Here's the whole story:
I bought a copy of Sims 3 Pets and started downloading it. I also bought a copy for Steam usfor the boyfriend which he accpeted.
The problem is, he doesn't have Sims 3 from Steam, he has it from Origin. We were unable to access the gift at all to see the CD Key on the gift copy of Pets so we could activate in Origin so I gave him MY CD Key which activated fine. He then returned the gift copy of Pets to me.
So now I need to move the copy I have registered to him and activate the gift copy I have on my account. Is this possible or did I just really screw myself over? I sent the problem to Steam Support but I don't expect much of a reply beyond "Seriously? Eff off."
