QTR-Quadtone RIP

Hello everybody,
I really need your help, I have a big problem with my color management
since one month.
I use Photoshop CS2 and Monaco EZ Color to calibrate my monitor and I
have problems of matching. Before creating my profile, if I open a
picture in Photoshop, I have the same colors and densities when I use
Windows RGB and Monitor RGB in proof color (and when proof color is
disabled) and if I use Windows explorer to preview the pics,
everything matches. When I create my profile and load it with
MonacoGamma and then open photoshop, it begins to be a real mess: on
BW pictures, the shadows are open even if the color picker indicates 0
to 10 RGB (or 99 to 95 Black) and the densities between monitor RGB
and Windows RGB don't match anymore in proof colors and I have to
select monitor RGB to have the same shadow densities than on my prints
done few months ago with QTR. 
Adobe Gamma is disabled, when I check in color setting, photoshop
seems to use the monitor profile created by Monaco.
Everything was working perfect few weeks ago and now I have this
problem. Can someone help me please?
