I made a large PDF slide show file (about 700MB) and then stored it in the "Outgoing Email Attachments" folder. When I went to find the folder using "Nero" to burn a CD, the entire folder was gone and so were the other folders: "Digital Camera Photos" and "Scanned Photos". In other words, I lost ALL my Adobe Catalog files!!! They are nowhere to be found. The images actually still show in the Catalog, but I can make no alterations, and I can't print them, I can't email them and the video clips don't work. What happened? I went to the recylce bin and clicked on the restore everything button and the folders actually reappeared, but empty. There were no image files.
