Error importing MDL into Blender 2.93-3.4

[RanchBurner]

I'm not sure where else to post this but is anyone else getting the following error when trying to use Fingolfin's Blender plugin to import an .MDL file?

Traceback (most recent call last):

Adding material to the mesh parts fixed it for me. You can read here how to add one: Exporting models from Blender using the MDL exporter plugin

Thanks for trying to help but this is an importing issue. Fingolfin did apply a fix recently but now I'm getting this error when installing:

Then when I tried to activate the plug-in, I got this second error:

Traceback (most recent call last):
File "C:\Program Files\Blender Foundation\Blender 4.5\4.5\scripts\modules\addon_utils.py", line 515, in enable

register_class(cls)
ValueError: register_class(...): already registered as a subclass 'War3BillboardProperties'

The installation process seems very picky to me. A video tutorial on here or Youtube would be appreciated.
