OK, I need help. All of a sudden - could be after I upgraded to the latest Lightroom iteration, I keep getting this message "There was an unknown error while writing metadata to this photo. Retry?" after I have edited my photograph in Color Efex Pro 4. If I "reset" then I lose all may changes. I can export to Flickr...but I don't like seeing the exclamation mark with the lines off to the left and really don't know what to do? I honestly can't say that this happened after the upgrade. I first noticed it about a week ago when I was trying out the GRD IV, so it probably was right after the upgrade.
