Activation of full/demo version

[techwynn]

I downloaded the full/demo version directly from this website. I want to activate it.

I have purchased twice now, from both gog and humblebundle, but neither purchase has given me a working activation key. Gog's purchase didn't even provide me an activation key. Humblebundle's purchase did provide a STEAM activation key but this key does not work to activate my game (and is only 15 characters long).

Please assist?

steam key versions still need to be installed thru Steam
