I recently updated to 5.7 and updated my RAW plugin and now my lightroom will not recognize jpgs as being in a folder. The jpgs that are there are gone from the list and then they show as "missing" from library when I try to synch the folder. I try to locate the files and there is nothing showing via lightroom - however I am in the desktop folder and they are there. I have renamed them and re-synched - that works, but then it loses that newly named file again and I am back at square 1. This is making me totally crazy because I don't know why it is not recognizing that these files are in the folder.
