QTR-Quadtone RIP

I recently updated my QTR software and went from PS7 to CS2.  I just 
created a new profile for museum etching using the curve eval program 
like always.  I created the profile but when clicking "Install 
Profile" I now get the message "This is not a valid color profile".  
Any ideas on what is going on?  I am using Windows XP.

Thanks,
Jenny
