Respecting "all rights reserved"

[OrbitalManeuvers]

I work in software dev, but not in open source, and not with VS/.NET. So at this point my abilities include being able to load a mod's source, fix the references, and recompile.

There's an abandoned mod that's marked ARR that I really want to use to make some videos. The last release is on Github, and I was able to get it compiled and loaded into 1.10.1, however it still doesn't work. Invoking it causes lots of nullrefs in some code that I don't know how to fix.

So that's where I'm bumping into the license question, even for my own personal use - because is it sketch to ask for code help in fixing an ARR mod for my own personal use? Pasting code in a forum message seems out of bounds, but anyone can look at the github and see the code at line 42 right?

So I guess I'm asking how it's viewed culturally to ask for help getting an abandoned mod working for personal use.
