Grimrock

I have made a simple model in blender. I try to export it with the grimrock model exporter from bitspyc. But I get an error, and the model file is 0 bytes.
What am I missing here?

When I edit an existing model .. it works normally when I export it?

is the hierarchy of the model correct ?, that is you have the Game Matrix node follow by the model itself ?

if not, when you go to the create tap there should be a legend of grimrock section that allows you to create the Game Matrix node.
