Shane, I'm having a similar but different issue or manifestation. When I open Evernote:

The main window (Notebooks) opens and is completely blank after briefly seeing the green progress wheel and will not draw. Notes open during the last shutdown open just fine. I can shutdown the blank Notebooks window but there does not seem to be an ability in the Menu to open another. I've shutdown every process that is obviously Evernote (it seems to do it just fine (automatically) on application shutdown.
After starting and shutting Evernote down multiple times it will eventually open and run ok.
Help. When I need to take a note it has to work..and quicly.
