QTR-Quadtone RIP

I'm running QTR on a MacBook Pro running OS X 10.4. I've been happily
printing since I originally installed the software a few months ago without
any issues.

I started building some new profiles today. I created a curve, started PS
CS3, and then made a couple of test prints. Everything was fine. I created
another new curve, restarted PS CS3, and now the QTR settings scree in the
final Print dialog box is missing. All I get are the following:

Copies & Pages
Layout
Scheduler
Paper Handling
ColorSync
Cover Page
Summary

The printer selected is Quad2200-K7.

The strange thing is that sometimes when I go to select the paper size in
the Page Setup screen, all I can choose in Paper Size is "Item1". This only
seems to happen when Quad2200-K7 shows beside "Format for:" (vs one of my
other printers). If I say OK to this, PS CS3 will crash.

I have done a complete power down, reinstalled QTR, reinstalled the latest
QTR and reinstalled the Quad2200-K7 printer.

Please help!

Terry.
