If you got the game through Humble or a bundle that gave you Desura keys, you should have access to a Steam Key now.

If you're old school and purchased the game directly from me back in the day, I'm working on getting you keys through e-mail soon.

If you have problems getting a key check out the community hub for a discussion on the topic with a couple workarounds for hiccups.
