Solving it took a bit mainly due to lack of understanding of what is really important in a complex system, what it is made of and how the thought process looks. Most of the time was spent delving into details that were unnecessary and made it much harder to come up with a solution.
Solution turned out to be very simple, very nice crackme :)

[Click to reveal]I think, the final function is totally time-based.
Am I correct?? I can't clear the final function.

[Click to reveal]This is amazing crackme, your mathematical chance of getting a match on any given minute is exactly 1 in 97.
a valid registration window only opens up roughly once every hour and a half (97 minutes).

I loved this crackme, it is complex and teaches you a lot of practical stuff. Even the fact that it needs a perfect timing makes it even more beautiful. I'm so happy 'cause it took me roughly 5 hours to find my way out, but it was worth it. Good luck, cracker!
