Lightroom displays gray thumbnails and Lightroom encountered an error when reading from its preview
Something is wrong with the preview functions of Lightroom. I've had the problem since installing the new version of Lightroom. I have followed all the instructions in this post: Lightroom error on preview cache or displays gray thumbnails (adobe.com) and the problem persists. I have uninstalled and reinstalled the program. Nothing works. How can I fix this?
