The image appears in the Camera Raw window. I click to open it and all that comes up in the workspace is the image's name/text but no image. When I click open in a new window I get a blank window with the same name.
Along with Chris' suggestion, if it does not work, can you provide the following info?
It all worked for a few weeks. Then nothing with any image whether raw or previously processed tiff. OS WIN 7. CS6, Nikon D2X supprted. In frustration I have gone back to CS5 which works with no problem.
