Hi, I'm hoping someone here can assist. It seems I don't have the masters of a lot of my photos that I am able to see when I launch Aperture. I'm hoping I can still use the photos, since I can visually see them on the screen, just not the masters. Yet everything I try to do I get the response that I'm unable to complete that without the masters. Is there a solution? It seems like the originals were deleted Thanks!
