All I had to do was kill the process "EvernoteHelper" and then Evernote was able to start. btw - this was on OSX 10.9.5

I'm having the same issue, which is not good as I've come to rely on this app. I've used Evernote for two years, accepting upgrades pretty much the same day they come out. I have not had any kind of issues like this previously.
