Here is my problem, I changed the location of my source folder and have been able to succesfully point the library to the new location. LRC warned me with question marks about all the folders missing sources in the catalog, with one exception, one folder; so I have no folder to point to the new location. The problem is that this previously synced item, contains 36,000 images, already cataloged, rated, etc.
Help! Any suggestions?
