I'm having problems importing files into my PE10. The error message is "nothing was imported. The file(s) or folder(s) selected to import did not contain any supported file types, or the files are already in this catalog." I don't understand . Adobe support doesn't answer phones, must still on vacation.
Well can you try copying a file and then rename it. And then try to import that file from the Organizer?
If it does, then the error message is correct.
