QTR-Quadtone RIP

I have used QTR for some time on an Epson 2200 with Epson UC Ink.  I
have just installed the new release and also installed IJM NK7 ink.  

The printer and printer model (Quad2200 NK7) are correctly selected. 
An image is clearly visible in the image window.  The complete path to
the image is also on the QTR screen.  

But when I click the Print button, I get an error window:  "You have
not selected a picture to print."

I'm running Windows XP-Pro SP2 with all current updates.  Is anyone
else getting this, and what's the solution?

Thanks.
