I am running Evernote 6.1.3 on a OSX 10.12.6. Everything was running fine until yesterday when the application started requiring me to login each time each time I ran it. Now when I open it, no notes display and the options under the window are grayed out. See attached. I am unable to sign out, view my preferences or do anything in the program. I have tried trashing the app and reinstalling according to the instructions on Evernote. I have also tried trashing my plist files from the preferences. The same issue comes back after reinstalling. Any ideas? It's a real show stopper. Fortunately, it is running fine on my laptop and through the browser.
