Hello everybody,

Here's a new challenge from me.
No obfuscation tricks this time, though code is a bit virtualized.
The algo inside vm, is more harder, than vm itself.

so the rules are.
1)No patching
2)No any sort of bruteforcing
3)Keygen only

enjoy! :)

btw, this crackme is tested only on WinXP SP2, but i guess it should work fine for any WinX system

Difficulty: 5 - Professional problem to solve

algo isn't that long, but it would take a while to reverse it :)
