QTR-Quadtone RIP

Hello all I have searched the history files in hopes to find a 
solution to my problem.  I am running Photoshop CS2 as of the last 
month and printing on a epson 2200.  I have had great success with 
Quadtone until my hard drive crashed.  I got back up and running 
purchased PS CS2 and started printing again.  Now, all my quadtone 
prints are an approximate 1.5 stops to dark.  I am running Grayscale 
20% or 2.2 dot pitch. My monitor is calibrated.  My color prints on my 
HP130 look great compared to my monitor so that is for sure calibrated 
right. 

Does anyone have any solutions.  Here is my workflow.  Save a 
grayscale image as a TIFF, open quadtone drag the image into the print 
area.  For my proofs I print on the Epson Enhanced Matte paper.  I 
select Matte paper, my printing model is Quad2200, My curves are set 
at UC-EEnhmatte warm 50 UC-EEnhmatte cool.  No ink limit or Gamma 
adjustments.  Does anyone see a flaw in my basic printing?

Thanks
Brent
