QTR-Quadtone RIP

I've read the accompanying PDF's over and over, and I can't seem to
make sense of them. This may be because it says the demo versions of
ProfileMaker will allow me to make and measure charts to create your
own linearization files. However, MY demo version of the program won't
load the testchart data reference files (i.e. - QTR-51-random.txt) --
I get "Illegal color data type" -- and "Measuring - Chart" is grayed out.

Any suggestions for where I can find information regarding creating my
own QTR profiles with an EyeOne spectrophotometer?

I have an Epson 7000 loaded with the "original" ICC Piezography quad
inks -- not the K6 inks. 

Thanks,

Nemo
