QTR-Quadtone RIP

I progressed somewhat. I removed CJ's curve and things started working.
I still have an issue with using more than just the one eboni ink. I
guess I just don't get it...
I was also getting weird results trying to print anything other than my
test image: any image save in Lightroom as JPEG refused to open QTRgui
and give a message "Unable to create JPREG Bitmap Buffer". Trying to
print any of my images resulted in them being cropped versions after
being Scaled and Placed. So I removed version 2.7 and installed v2.6
which doesn't do JPEGs but TIFFs instead (the user guide doesn't mention
this because it is based on v2.2). Now I don't have cropping issues and
I can print a correctly scaled version of my images albeit they are very
dark.
I am having mixed results using QTR: The sliders in Advanced Adjustments
say Lightest and Darkest which means nothing in the context. Does it
mean that pushing the slider to the left will lighten the ink
density(midtones) or gamma (shadows)?
Is there a later version of the UG anywhere or a tutorial with lots of
screen graps? Some of the explanations of how to start working with
curves I am sure make sense to someone in the business but it is very
confusing to me.
ANy help appreciated
