I have found a serial that works, but I'm not really sure what goes on in this crackme...

Yes, it's not hard to find working serial :)
Algorithm is not so obvious. (comment can help)

I have just solved it! It was awesome. I have generated a very simple serial:
k00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000F

I am too lazy to 'write' a tutorial, but I have uploaded a screencast tutorial to Youtube.
