Original Files Unavailable
I have been using Aperture for several months now. I have imported and edited hundreds of files without issue. I have not changed any settings that I know of. Aperture is using the iPhoto Library at this time.
I imported a series of images into a new folder. I went back to edit them and none of them are editable. I can't export or any other operation. It always states that the originals are not available. I have cleared the cards that the images came off of so I can't reimport them.
There are icons in the corner of images in Aperture in the lower right corner. Is there a list of what they all are and what they mean any where? The icon that is showing is an arrow curving from the lower left to the upper right and what looks like a small lock.
How can I get these images back and able to be worked on?
