Reading ANSWER TREE .atp files with SPSS 18

lp326
I have an old version of SPSS (14) at work and a separate package for decision trees (Answer Tree 3.1) which produces .atp files.
I have sent these files to colleagues who have version SPSS 18 which has decision tress built in rather than in a separate suite. They cannot read .atp files , is there any way they can be made to do so?

Many thanks in advance for your help,

Best wishes
Luigi

What does this .atp file look like if you open it in notepad/wordpad/vi or whatever text editor.
Does it appear to be something which a set of human eyeballs can make sense of or is it some sort of binary gibberish.  If the former then post an example of said text file (please a simple model, not one with a bajillion predictors) and maybe SWPIM can help make sense of how one might translate such into SPSS compute/if/blah blah blah.  
Please reply to the list and not to my personal email.
Those desiring my consulting or training services please feel free to email me.

atp files are binary and cannot be read by SPSS Statistics.
