This is the same as #2...Rename 'JNE' to 'JMP' and it will automatically become registered. 

As the same for my #2 I also created a patch for this but using a different patcher. I used AT4RE's Patcher.

Using:

IDA Pro v7.0

Search for 'Unregistered' -> Find Verification Function -> Patch JNE to JMP using IDA's patch function -> Save -> Cracked

 

Sadly, i couldn't find the original password.

The password is obfuscated by not bad algorithm and takes time to solve so i passed...
