Anyway to fix unreadable level.dat file?

[Inktpleurer]

When I run region fixer on my world the following happens:

C:\Users\Inktpleurer\Downloads\region-fixer> python regionfixer.py -p 4 --delete-corrupted C:\Users\Inktpleurer\Downloads\Server

I'm having the same issue as well, which is important because I have a world I have worked on for so long and I don't want it corrupted. does anybody know how to fix this issue?
