Digital BW, The Print

I am using Silverfast Ai version 6.01 r28 - the PS plugin version 
Polaroid Sprintscn 120 with latest firmware
Photoshop 6.01 
Windows 98SE & 768mb ram 
Scanning in Normal mode, not Normal(file).
Mainly 16 bit Grayscale scan type.

Problem is that after the scanner finishes scanning , the little blue 
progress bar shows that it is finished, then nothing happens ! It is 
almost frozen ! 
IT DOESNT BRING THE SCAN INTO PS! 

The little Blue progress bar is complete. 
A thumbnail of the image is complete. 
And the little aeroplane with moving propeller is still flying. 

If I click the Cancel button, it will often do what was supposed to 
happen - bring the image into Photoshop. 

any ideas ?
(dont suggest contacting Lasersoft - done that, no response)
