I normally import everything into the Aperture library, but apparently a few times I must have imported referenced files, which I no longer have. Since that happened, I've wiped my hard drive, sold my Mac, and bought a new one. So no chance of recovering the original masters. The photos are all "there" in Aperture, but I can't do anything with them, I just get an error that Aperture can't locate the referenced file and the master is offline. Is there any way to use the preview version stored in Aperture to recreate a new master, even if it's lower resolution? I went to the Genius Bar today, the best they could come up with was to do screen shots of the images to create a new jpeg, then reimport. Gotta be a better way than that, no? Hopefully someone can help... Thanks in advance.
