Can't find Serial Number

[Zoob]

Well I actually bought a copy of this game a while ago. Just bought a new PC and downloaded it into my library again. But when I go to play it, it is asking for my serial number. I searched my emails and can't find it. How would I go about retrieving my serial number?

Right click your game in your library, then you can select "View CD key" :)
