| I believe that many people like your crackme, I find it very entertaining! In case you wrote that because of the low quality rating: don't worry, I have the impression that there is sometimes a hater around who gives all crackmes bad ratings and also lowers the difficulty – it has happened to me too. If you look at the other crackmes: many of them suddenly received bad ratings overnight. Strange, right? It would be best if everyone would rate, then intentionally bad ratings wouldn't have such a big impact. When writing this you had a 2.5 quality rating which is disrespectful and inappropriate, i will give it an upvote! |

| @ nightxyz: The crackme works fine on your notebook, it is the expected behavior. You should finish reversing it on your notebook!
I don't know why it doesn't work on your desktop pc, i am sorry about that. |
==> |
| @nightxyz : The behavior that the serial number does not work on your notebook is correct! Can you try debugging the crackme on your notebook? Because i dont understand the behavior on your desktop computer... |
==> |
| @nightxyz : lets continue on discord, i cannot answer here without spoilers |
==> |
| @nightxyz : Fully close the debugger, restart the exe and try again. |
==> |
| @nightxyz : PS: If you figure it out, please let me know here but no spoilers please! |

| @Oscar404 : Don't give up! :)
@nightxyz : The serial is not working, probably you have missed something ;) |

| @Yanderome : Since no one has posted a comment here, I almost gave up: Is this Crackme too difficult after all? I’m all the more happy about your solution, thank you very much! It’s well-written and detailed, and you really understood every little detail. I’m very impressed with your reversing skills, as this is by far the hardest Crackme I’ve made so far. I’ll have to come up with something... |

I will give you 2 hints:
1.) You don't have to reverse the CRC32 algorithm
2.) Click the 'About' button and read the information carefully

| I know, but what can i do? It's because protections often use similiar techniques as malware do.
You can either trust me, or use a vm to debug the crackme- |
