QTR-Quadtone RIP

Hello,
I'm running 10.5.5
I printed a 21 step wedge with my created QTR curve applied.  I read the wedge using the 
measure tool & saved the resulting file  info as text file. I then dropped that text file into 
'Create Icc' script within QTR. It produced an icc profile (.icc with the icc icon). Then  I  put the 
profile into the profile folder  .......Library>color sync>  profiles.  Same procedure as always.
When I try to use it in PS4,   View>proof set up> all my profiles....... it doesn't show up.
My question is why doesn't it appear. I've done this with my curves in order to soft proof, but 
wanted to try this to see if it was better than (more  accurate) than using my curve as a soft 
proof.
Thanks
Joel
