Suddenly can't see graphics when using Frame 10 on a particular machine

Upgraded to Frame 10 (from 9) on a Windows 7 x64bit machine about a month ago.  But suddenly today, I started having problems with Frame not recognizing .PSD images in files.  Then it suddenly decided it didn't want to view any images.

I was able to open the files on another machine and they worked fine - so it does not appear to be the files.  I don't get any crash errors from Frame - it just gives the usual mumbo jumbo about it can't display some graphics and they show up as grayed out.  The object properties still map to what is a valid file.  I'm stumped.

Happen to anyone else?  Anyone else have an idea why it happened??
