Digital BW, The Print

I want to use the UT14 ink set (don't have them yet) with my 1400 and am going over Paul Roark's "Embedding Photoshop Curves in ICCs" procedure.  I opened the rgb-raw-16.psd file in CS4 and am trying to place one of the acv curve files on it. Image>Adjust>Curves>Load doesn't seem to be available in CS4 and if I drag and drop or try to open it I get, "could not complete your request because of a program error" message. In fact it or something caused my Win 7 64bit machine to completely crash with a brief message about my graphics card.

What is the proper way to do this?  I must be missing something.

Thanks
