I followed the directions to delete the Evernote folder from Containers and re-install. The result was that Evernote launched, immediately posted the nasty message, and when I tried to Force Quit EN relaunched itself! Eventually I noticed three different instances of EB in the Force Quit list. I checked and there has not been a new Evernote folder installed in the containers directory. WIll try that older version tht someone posted ... and will look into an alternative
