[EpiData-list] Files won't open on remote computer

[epidata-list at lists.umanitoba.ca]

I create qes/rec/chk files with 1 respondent and send to a data capturer 
via email.
She has problems opening the files in EpiData.
We are both on Version 3.1 / Windows based.
Any ideas what could be causing this?
She can make the files on her machine with no problem and send them to me.
Regards
