Digital BW, The Print

Unless my eyes have deceived me, I've read that it is possible to
build a profile for Cone K7 inks for QTR using PRINTFIX PRO's 225
patch pattern.  Because I use Cone K7 inks, obviously the calibration
print is all b/w.  After measuring all of the patches, I try to build
the profile.  The progress bar jumps to about 50% and never moves. 
I've left it running for up to 10 minutes.  


The user documents suggest that not completing the build process will
happen if the measurement file is bad, but I've remeasured three
different times.  I am confident I have the right number of measures,
so I'm at a loss unless the all greyscale readings are what is causing
the problem.

Anyone else had experience with this problem?

I'm using PFP on Vista, but I've uninstalled/reinstalled and cleaned
the registry between installs with no effect.
