ConceptStation crashes while exporting file

I am exporting file and it creates most files but crashes when it gets to tin file or inpx file. I am trying to test the file and see if/how it works in VISSM, but can't get the inpx file to try it. I have exported other files and they export fine, but not this particular one. Any help would be appreciated.
ConceptStation ver 10.00.07.30
