Old bundle key from Humble Flash Bundle: Boo!

At this point I'm hoping it works. Given the dates listed, I'm pretty sure the bundle was released after I got it on steam, but can not find where I got my steam version. Hoping the version I have on steam came from BlinkBundle, but since the website went down some time ago, I can't check what bundles I bought off Blink anymore. Pretty sure key wasn't revealed until before I started the giveaway, but not entirely sure anymore.

Found an old list of keys I got from Blink, and Zafehouse is on that list, so key should work. That put my mind at ease.
