QTR-Quadtone RIP

I am printing the ink seperation page in trying to make new curves.  It 
has suddenly stopped prining the #6light magenta line.  All nozzle 
checks are good.  It is not even printing the black lettering for it.  
For that matter it isn't prininting the lettering for the #7 or #8 
positions that it normally does.  I am using a 1280 with UT2.  Only 
change is from matte black to photo black ink.  Any ideas?  
Thanks,
Peter

Anyone have any ideas on this.  I've tried everything I can think of, 
including getting a new version of QTR.  This is driving me crazy!
Thanks,
Peter
