So you mean some FBX files work and some don't? Are you using different options when exporting them? Especially check your options for exporting tangents as that was where it crashed before.

Sometimes the FBX file doesn't import the object with its textures so you have to apply them manually. I have played around with the export settings and I still get the same result. The object still works even though the textures have to be applied manually in the model editor.
