Import 3dm add-on for Blender,Error

Hi,I just download an add-on for Blender to import my 3dm.file to Blender.But It turned out to be an error. I’m not familiar with Blender so I cannot figure out why.

Moved to Rendering category so the right people will see it.

The current release is v0.0.7 ( https://github.com/jesterKing/import_3dm/releases/tag/0.0.7 ). Make sure you download and install the correct zip file for Windows.
