QTR-Quadtone RIP

Has anybody else had this issue? --  when trying to print, the Photoshop "Printer Profile" dropdown menu does not contain "QTR Gray Photo Paper" or "QTR Gray Matt Paper" -- which according to the documentation for QTR 2.6.2. are required to be used for printing.

Following instructions in the documentation, I copied "Gray_Matte_Paper.icc" and "Gray_Photo_Paper.icc" from /Library/Printers/QTR/icc, to /Library/ColorSync/Profiles.  The other QTR icc files in or linked to /Library/ColorSync/Profiles do appear in the "Printer Profiles" menu, but "QTR Gray Photo Paper" and "QTR Gray Matt Paper" do not.

I am running CS4 on OS-X 10.6 and QTR 2.6.2 with Snow Leopard Patch installed, to Epson R2880.
