Winpilot pro and Ipaq 4700 locking up.

I am trying to run the latest version Winpilot pro on an Ipaq hx4700
and am having trouble with the program locking up and freezing,
leaving the Ipaq useless till you do a soft restart.

The Ipaq is wired directly to a 302.

I am using a Windows Mobile 6.1 operating system. I have been told
this may be the problem.

For the last week I have tryed to reinstall the WM 2003 operating
system that came with the Ipaq, the best luck I
have had is downgrading to WM5.0 which still crashes.

Has anyone here succesfully downgraded their Ipaq to WM 2003? I would
like to find out where you downloaded the program and how it was done.

Thanks for any advice,

Joe Simmers
