You seem to be assuming the code only checks once for serial numbers.
And that you can find that section of code.

I think it would be very easy to do the check in several places (200 or so).
And instead of bombing out, set a flag which causes slightly incorrect
answers to be produced.

In addition, the serial number could be stored in weird ways in many
places. If you let a friend copy your disk and he was caught, you (the
original purchaser) could be identified and would share the guilt.
