I just bought a laptop with Windows 8 and installed Photoshop Elements 11. Previously, using Photoshop Elements 7 on a Windows 7 machine, I did a full backup of my catalog to an external drive. The files in this backup folder are: 1) numerous photo jpgs, 2) a catalog.buc file, and 3) a backup.tly file. There is nothing else in the folder.When I try to convert/restore this catalog into Photoshop 11 the catalog manager does not detect or recognize the backed up catalog. Is there a problem with my back up files? Is there a solution for the failure to detect the catalog?
