hi n30,

what you are doing is not reversing the tool for security bugs, it's
traditional cracking stuff.
my opinion is, that this can't be reported directly as a security problem,
but you can point out that
they should improve there software with a harder copy protection, such as
runtime binary
encryption, anti-debugging stuff and so on.

cheers,
