QTR-Quadtone RIP

Recently my MAC laptop crashed.  I believe I had an earlier version of
Quadtone Rip 2.4.9. running on it.  The crash made it necessary to
reinstall a new hard drive and programs.  I have installed the latest
version of Quadtone 2.5.1 and will now have to rebuild all my
linerization files. 

I have noticed that the Quadtone mode pull down menu no longer
displays "calibration mode" but rather four different mode choices.
Referring to latest 2.5.1 reference manual dated Feb 2007, it still
refers to the "calibration mode" option.  This does not correspond to
what I am finding on the actual program as it runs on my computer. The
dialog boxes do not match the instructions in the manual.

The question:  What is the correct calibration procedure using
Quadtone 2.5.1? 

Thanks in advance,

Mark
