WF here is my cd key?

[Predicted]

Hey guys, did a quick search on this but didnt appear to find a topic on it.
A while back when I saw DoF on steam greenlight i bought the game, but seeing as my computer was pretty damaged at the time I didnt bother installing the game.
Now however I bought a new compuater and was looking forward to playing, but however I dont seem to be able to locate a CD key, anyone care to weigh in on the problem?
