I've edited my NEF photos in lightroom and have tried to export to a formatted CD. When I try, I have several issues. I either see in the top left corner that the files are ready to go to CD but there is no further instruction or I get the pop up message that the files are offline or missing??
Just for background, in what format are you exporting your images? Also, are you able to export them to your hard drive in your chosen format? I haven't tried exporting directly to CD, but if you're able to export to hard drive and copy to CD, that may be one solution.
