I am trying to import files from an external HD to LR through Bridge. Usually I select the files for editing and drag them into LRcc. I have been doing this for years now, until today. Now I am getting error message that I don't have permission to import the files. I have not updated software or hardware since last use and have not changed cameras or drives. I have not altered directories on source HD. Confused as to what is different from my typical workflow.
