After a crash and restore last week (latest version of Aperture and, of course, Lion), all my projects and albums in Aperture show up, but there are nor previews, and when I try to locate the referenced files (all stored in their locations on the drive - not the Aperture library) I get the following message: "The selected master images are either offline or not found. Please reconnect them and try again." The images in question are still whey they should be.... I tried selecting the "Locate Referenced Files" command under the "File" menu. But when I navigate to the images I want to reconnect, the reconnect options in the "Referenced Files in Selection" window are greyed out and I really have no idea how to fix the problem. Oh and I tried Apple's other "try this to see if it works" troubleshooting tips to no avail. Any help would be very much appreciated! Brad.
