Got the key from Humble Bundle long ago. I really hope I've never send it to someone else and that it's still valid. So sorry if it's not. I don't know a way to test it though.

if you or a friend owns it, then you can attempt to redeem the key. If you try and redeem a key for something you already own, the key will still be valid if it says that it's unused. Really handy way of testing valid keys.
