This looks like the same issue as #23 . The resolution was to remove the quotation marks from line 12.

I haven't tested this, and I'm only a beginner with writing Blender add-ons, but it seems that declaring __version__ in this file is inappropriate. Normally, the add-on version is declared in the bl_info dictionary, described here in the developer documentation.

@Efala @YoursTruely would you mind testing the latest develop - I believe I've found the culprit and fixed it.
