I have been having the same problem since November 7. When I start EN, the loading icon appears but never ends. Not a single note appears.
I uninstalled Evernote, deleted all EN folders (%AppData%/Evernote and %LocalAppData%/Programs/Evernote) and reinstalled. However, the problem is still not resolved.
This is the worst trouble. Please fix it immediately!
