Please note if your version of Protel uses
only a single "D" in the %ADD, your version
requires a patch update.  Or you must ensure
that the Aperture file is sent along with your
data as the format is invalid. 

You could correct the error with text editing 
the Mass Parameter line with a Search & Replace 
Find %AD and replace with %ADD
