Adding photos to catalog that are supposedly already added.
I somehow had corrupted my catalog so I was able to use an older one. Fortunately I have the thumbnails and the keywords. So if I were to pull up a keyword, it will pull up the thumbnail, but if I go in to Devolop it, it says "File no found". If I go to the Import dialog and choose "Add" only and find the photos on my external harddrive, they are all dimmed out, and I can't add them to the catalog so I can develop them. How do I "Add" them to the current catalog, but I don't want to move them or do anything else.
Thanks.
