Looks like you may need to flip the normals on some polygons. select the black polygons and use polygon tools flip normals Like I'm say that's what it looks like to me.
z-chasing -- multiple overlapping polygons?
NI don't have a zip utility on my Mac...
Hi.
You did it again
Scale the model down to x, y, z=0.05 and you will succeed.

Group scene and scale down the group folder, ungroup if necessary. Done.
Don´t know. If everything looks fine except the scale, why one should going to export it again?
