The only solution is a working keygen as always!. Patching is not allowed. Prizes: 1) Keygen: Gold 2) Serial: Silver Winners: To be decided... Screenshot : Have fun!

It was a piece of cake to work backwards after that, hardware breakpoints are great. I eventually learned the algorithm and how long the correct serial should be.

September 21, 20177 yr i am stuck at VA : 00455224 It looks like a procedure where generates a valid serial number. I stucked here. It is so complex for noobs like me. Can some one please explain how this algo works.

It is so complex for noobs like me. Can some one please explain how this algo works. It takes a serial-number vector (the parsed serial number) and the name-checksum string, then runs the algorithm on them to produce what is supposed to yield the same result as the name-hash. If the hashes are identical, the serial is considered "correct". Here's the full solution for reference: https://pastebin.com/6KCfACR4 Edited September 21, 20177 yr by VirtualPuppet
