Blender Exporter 5.6.2 problem on blender 2.79

[mandim]

Hello,

I have just updated the last version of blender exporter and I'm not able to export a simple scene.

This is the error log I get:

Exporter version: 5.6.2, Blender version: 2.79 (sub 0)

What I'm doing wrong?

Attached is the .blend file.

Thank you in advance...

I didn't know that I had to restart blender in order to work...

Sorry for the mistake.
