i just purchased the newly released full game once I received the email that it was now available. i received the product receipt/serial number but was NOT given the option to download the game.  where do I go for that?

I received the "Your Product Keys" email after looking in my Trash/Spam folder, which brings me to Steam despite ordering directly through Stardock after clicking the link in the email.  Once I sign into Steam I do NOT see the game anywhere in my library.  I should have purchased it directly through Steam to begin with. Really disappointing.  Unpolished release.  This should not happen.  On my Stardock page I still have download links to every purchase I made going back years... but not for this game.  Why does the download link direct me to Steam where it's not even in my library?

Figured it out: activate the key they sent you in your Steam account. I won't detail how I got there, but it was as frustrating as my last port, but now I have the game!
