Hi, I found the pass which was really obvious and I just have a question:
I have found (I think) which jmp I need to NOP but do I have to NOP it first and then run the app and insert the password or do i have to run it --> insert password and then NOP the jump. No matter what I have tried, nothing works. Also, how would I get the checksum with olly? Is it possible or do I have to save the changes to the file and then check it?

Thanks in advance for any help.

It doesn't matter when you NOP the jump. You need to save the changes to the file, either with Olly or a hex editor and then use md5sum or something to get the checksum.
