When I try to build a profile after measurements I get the following 
message:

Unexpected error NilobjectExeption has occurred at code location
[001:000]PrintFix pro will now quit. Please report this error, and 
relaunch PrintFix pro.

I restarted 3 x but no success.

Background info:
PC with XP pro latest updates. AMD 6400 2x 3800+ with 2 Gb ram
Have done some successful profiles some days ago!
Looks as if the Spectrometer is Ok because I was able to measure the 
150 patch target.

Any thoughts on this problem?
