I am using PE10 on a Macbook Air running OS10.7.4. Everything was working well until I made a mistake - renamed files when "show all files" was checked. So I renamed not just the files in one album, which is what I was trying to do, but renamed all files in the catalog. I then went through each album and renamed again, to get back to where I started. After that, backup/sync would not work, and the backup/sync preferences would not display -- just an error message telling me to close the preferences and try again -- which produced the same problem.
I tried uninstalling and reinstalling -- no difference.
I tried trashing the preferences files in the ~/Library -- no difference.
Does anyone know what's going on?
