Thanks for the information... Since I had other variables that changed, I decided to recreate the curves through a bit of trial and error. It seemed the best way so crack that nut.
This poses a possible feature request for the QTR and/or Print Tool programs... Develop a tool to automatically export all the relevant print information (QTR curves, blends, etc.) into a txt file or similar that can be placed in the same directory as the image file. That way, you can get back the settings later on even if you have changed computers (which was the case for me).
