I know what "Das password ist richtig" means, but what's the following:

Jetzt das passwort in Kleinbuchstaben als Losung eintragen?

I patched it using W32DASM btw :)

I've made a tutorial for finding the correct serial. I am a total newb when it comes to reverse engineer and just started cracking 2 days ago and english isn't my native tongue, so be gentle :P

I'm not sure about the code, I don't know ASM, so I googled most of it when writing this tutorial, but let me know what you think. Any suggestion/critic is welcome!

Thanks for the CrackMe MiB!
