**the short edition to the solution i've submitted: in case 0x3F+1==0x40 (i believe it's true :)) i really looked for a hamiltonian path, not "only for the 0x40-path". Maybe this graph has a hamiltonian cycle and in that case a fast keygen can be written after precalculation.

nice, nice. :)
How much time you spent to find the serial?

I spent 2 nights reversing the program and 2 nights building a keygen. I thought that it would be very difficult to find a key, but a 3 minute brute force led to over 500 keys.

Very nice!

I based this algorithm, in this chess problem:
http://en.wikipedia.org/wiki/Knight%27s_tour

And it haves a non-bruteforcable solution. :)

If it is so, then ok :) But a more deteiled look is needed to find this out
