[AccessD] Filemaker ODBC Driver for Access

Guys,
 
Does anyone know where to get an ODBC driver for Filemaker Pro? I have a
client who is migrating from Filemaker Pro to Access (Government Dept)
and they would not know where to get the disk that was originally
installed on their PC. The task of extracting the data from his FmPro DB
into Access is part of an app I'm building for them.
 
I don't want to purchase one if I don't have to, but the only ones I can
find online are $100+. For one file and one import instance I can't see
that that is value for money...
 
Any help greatly appreciated...
