Yiurt

Well, I got a email back from support and brought a key online for 10$ as a discount, atleast I get to play the game I paid for now.

I've brought the Entrenchment and Diplomacy expansions for Sins (online), but turns out I never registered my game and can't update it! The box is long gone, so I don't have the key for registration. Is there some way to remedy this problem without buying another game just for the key?
