Digital BW, The Print

Hello,
I just downloaded and installed the Windows version of Quadtone RIP 
and the GUI v 2.1.7.

Until now, I used the old way of dragging the icon to the batch file 
and got a wonderful print.

Now howver, I am trying to use the GUI and when I try to print using 
this interface, I get absolutely nothing.

I click image, select the approptiate image (grey scale, tif 8 bit 
that printed with the old method) select the appropriate paper I am 
printin on, click the Print button and the image disappears from the 
preview window and that's it.  Printer does not make a sound (yes 
it's turned on), no printing at all.

What am I doing wrong? 

Thanks for any help anyone can give.
Randy
