Thanks for digging into this further. The support e-mail for DIFx Tools is difxt...@microsoft.com. I have received responses over the years from different people, but never any resolution to my problems. If that e-mail address is no longer valid, then I can give you the addresses of the specific people that replied. Please keep me posted on what you find out.
