Have an interesting problem...
In my working LR catalog, all of my folders save one have disappeared. Obviously, this would normally mean that the images have been removed from the catalog and must be re-imported, but here is the interesting bit. The photos are still actually in the catalog. If you click on "all photographs," the photos are all still in there, but there is simply no folder in the directory corresponding to the photos.
I tried removing one of the weddings and re-importing is, and that made no difference...they are still only visible in the "all photographs" tab.
