Digital BW, The Print

I have been using Roy's QTR Create ICC for profiles to print on the 
2400 from CS2 with great success.  Photoshop CS, however, does not seem 
to "accept" these profiles.  If the profile is entered as the print 
space in CS, the program automatically replaces it with Gray Gamma 2.2 
after going on to the next print dialogue.  This is true of any profile 
I create with Create ICC and also true of Roy's older profiles like 
Gray matte.icc.  Other profiles "stick" in CS.  Any thoughts on this?
