Trouble importing sketchup model

Whenever i try to import my new sketchup model draft, Cryengine does not recognise.

The .cgf file is missing, when i try and import. My play up settings and filepath is correct.

found this troubleshooting page which helped guide through certain issues that would potentially stop cryengine from importing model.
https://groups.google.com/forum/?fromgroups#!topic/arch1101-2012/ryUcUrefVHo
After going through everything, I still cannot import.

Component name: bridge

the component was originally created with groups to keep things organised and then nested that within a component and exported. did not work. 
also tried exploding groups, then make whole structure component and export. did not work.

This is component statistics

I don't think there is any bad geometry. I checked normals on the playup toolbar. here are some screenshots of model. (no bad geometry)

Any help or advice would be greatly appreciated.
