This evernote release 184.108.40.20612 is full of bugs. Very slow. Errors syncing. Clipper not working. I had the same problems. Removed Evernote completely, including database. Then install previous version 220.127.116.1120 and sync. (it takes few minutes, depending on your database size and internet speed). After doing that it works fine again. I'll wait for a better release to update.
