Import works fine except for this one file

The exporting and importing function has been working great for templates that I create within my WP account. I had a designer create an ATA template, export it, and email the .txt file. However, when I attempt to import her file, I get an error message stating the file does not appear to be an Atahualpa settings file. I have attached the file for your review. I am not certain what version of WP the designer is using or if that could be having any affect. Thanks for your help...
