Hey there,
That error message usually means that something Cshell.dll tried to load isn't there. (It's a confusing error I know, I can't change it, Sorry!)
Make sure all the files/folders are extracted into your NOLF directory. (SDL2.dll, CShellReal.dll, Lithfix/, etc..)
Disable any custom rez files in Advanced -> Custom (Like modernizer.rez!) and make sure the command line says:
-rez Lithfix
That will make it load from the folder called Lithfix instead of trying to load a .rez file.
Odd that it works in one, but not the other though! Hopefully those steps will fix it for you!
