Steam lost my Fm 14 info?

Hey guys, got a weird situation here. It's been a while since i've had the GM bug, but i've had a cankering to play it lately, but when i went to load it in steam, i noticed it's no where in my library. Now this is a game I had bought back when it was on sale for the beta event, and it's been a long while since i looked for it. I checked the steam support pages, but the advice largely pertains to new purchases, and making sure you're not filtering out the game for some reason which I'm not, i've searched my library for it multiple times on multiple days. compounding the problem is I can't remember how i had originally paid, if i bought through steam, or bought on the site and entered the key. Is there anything someone in an official capacity can do to help me sort it out?

Do you have more than one Steam account?

Are you logged into the account you bought FM14 on?

Aside from making sure of the above and checking you haven't filtered out your library there isn't much anyone can do for you here as its between you & Steam.

I do not, and I am. and since i'm unsure of the payment method, i've got a feeling i'm pretty well hosed then :\
