Thank you for updating your instructions. But they appear only replicate what I have already done. Still getting this error.

I put my thinking cap on and did this. . .

I appear to be rendering now. Phew!
I appear to be limited to a single thread on my machine. So I'm only using 17% of my computing power. It looks like an option for the blender plugin is to have an "auto thread" checkbox. Is that something you can add to your plugin?
