Thus you need to collapse the UVW Unwrap onto your Edit Mesh otherwise it is not applied to the Edit Mesh and will not get exported.
I have exported it successfully using a b3d exporter for max, seems as good if not better than kwxport, have yet to fully test them both. Also updated the max file, the unwrap now exports

Its been a hard road, but hopefully it should work now
