Digital BW, The Print

I have created a number of these profiles with no problems. However I 
can not get HPR profile to work. It output a virtually black print!!!! 

I changed over the black ink today for mk, and created two profiles, 
one EAM the other HPR. Both created using the same workflow. The EAM 
profile works, the HPR doesn't. I have tried just about everything I 
can think of but cannot get the HPR profile to work. Something is 
corrupt but I cannot see what the heck it is.

Any ideas.
