Mike, Thank you for the suggestion to download the app from evernote.com. I had the same issue: upgraded both Yosemite and Evernote and Evernote would not longer start and would just crash. -eileen
I'm using the paid version and have the same problem. I've lost three very important notes now and I've only been using the app for a few months now. I haven't been bringing paper to meetings anymore because I was relying on EN and taking notes on my iPad. Now I might have to go back to using paper....EN please fix!!!
