Digital BW, The Print

Roy,
Your RIP just keeps getting better and better. Thanks so much for your work.
I have been using your previous lab grayscale as my workspace, and it seems great. 
I downloaded this one, but Photoshop wouldn't load it into color space. So, I'm 
uncertain as to how to use the gray icc profile as a working space.
1. Is it significantly different from your last one?
2. How do I get it into my colorspace settings? when I try to load it as I did your last 
gray profile, the file name is grayed out (Mac OS 10.2.8)
