mjcteleblender - please help

I've been trying to get mjcteleblender to work but keep having the same issue. It exports the object and materials fine from DAZ but doesn't create the matLib.blend file which is essential for it to import the materials into Blender.

When I run the mjc script in Blender it just brings in the scene without materials and the script fails at mcjBlendBot.loadfix( "F:/daz_tests/scene.obj", "CYCLESMATS", "F:/daz_tests/matLib.blend", True ) because matLib.blend doesn't exist.

I'm on an unusual setup in that it's a work PC and I don't have admin rights. I getb temporary admin rights when I need to install something. Could this be the issue?

DAZ (4.10) is installed on my C drive (solid state) and my DAZ Library (and the mjc scripts) are in c:\\Users\Public\Public Documents\My Daz 3D Library

I run Blender from my F drive (disk) and it runs like a portable App (i.e. not installed in the registry).

Both the mjc and the blender scripts seem to work fine it's just that no matter what options I try, or destination paths I choose, the matLib.blend file isn't created.

I'm on Windows 10 64-bit. Any thoughts.
