I am having issues with my Lightroom catalog. I am able to open the catalog normally, however, when I try to export the image an error message pops up saying "Some export operations were not performed. The file could not be written." I updated my Lightroom application to the newest version and then was prompted to update my Lightroom catalog as well. Unfortunately, this did not solve the problem. I was only able to export a few photos properly before the same error message popped up a few minutes later.
In the screen shot above I was actually trying to export the image as a PSD. I am not sure why it shows that I am exporting the raw file. Below is a screen shot of the exact settings I was using to export. I also tried expoting as a JPEG and PNG and got the same results.
