Jed,
thank for that information. I deleted that folder and still got the error message. I have attached the new log. Would converting some of these to dng help?
I don't see any filenames listed.
You could try selecting the first half of the images and see if it works, then select the second half and see if it works, dividing each half into a smaller half until you find the image that is the culprit. (it's a binary search)
Of course, you shouldn't have to do that and the error should display the name of the file that is causing the problem. This needs improvement.
But, based on the message, it's likely an item that is referenced by your catalog that no longer exists at its original location.
