'an error has occurred' when updating Evernote

[willcan 0]

I went to update Evernote yesterday through the Appstore but it failed to complete. It automatically closed Evernote when it started the update. Now I cannot open Evernote. It says 'Evernote is currently updating'. In the Appstore it says 'an error occurred' next to a dark grey button 'update'. If I click on update it comes up with a box saying 'Evernote failed to download Use the purchases page to try again'. When I go to the purchases page and click on update it comes up with the same box.

How do I fix this problem or open Evernote?

First,  make sure you have a backup of your database - especially any unsynced notes - and raise a support ticket (see below).  Then try uninstalling and reinstalling the software.  If you're on a desktop,  try the download from Evernote.com.
