I upgraded to 5.4 today via the update notification inside Evernote...when the program tried to restart after installing update in froze my entire system. I then waited about 45 minutes and it never recovered, all other applications frozen also. Rebooted, and system was fine until I tried to load Evernote again...then same problem. Rebooted and download the update again from the web, copied over existing install and tried to reload Evernote...same problem. Any one else having these problems? Previous version worked fine prior to install of 5.4. System is OS X 10.8.5 on Mac Mini Server.
