batch renaming stopped working

Still another problem with the multi-bug-ridden program Bridge CC that is part of the subscription scheme.  After hours and hours of correcting wrong dates that it assigned to videos - where there is no thumbnails so I can't even see the subject, unless I go to CS6,  I was ready to put species names in front of the unique file numbers assigned to each file.  I did Waterfowl, then Owls, then was trying to do some squirrels and nothing happened.  I tried deer.  Nothing I tried to close Bridge and it won't close.  I can paste the desired name to a single file but batch stopped working.  To close I will have to use task manager and lose the search selection that I had made and start all over.  I think 6 hours or more trying to do what normally would be expected to be one hour with CS6, which worked far better. (But can't read Z7 files)
