Windows Mobile 5 with filePro?

[Transpower]

I purchased my first Windows Mobile 5 device, and downloaded and 
installed PocketDOS.  I then copied (using ActiveSync) filePro 4.1 DOS 
programs and data files to the s: drive on the device.  I put p.exe on 
the c: drive of the device and also fppath (with s:, s:, ).  When I load 
p.exe, the program loads, but when I attempt to IUA a file I get the 
message "*** A filePro Error Has Occurred *** On File: /filepro/COOK/key 
file not found."  (I haven't seen this sort of message for years, 
needless to say.)  I tried various other fppaths (like / or s: on the 
third line) without success.    So, what's the solution?  It's got to be 
fairly trivial.
