I'm from Germany. Please excuse my writingerrors.
I have the same Error-411-problem with Sticky Notes and the activation of my Evernote account. I get in contact with Evernote-facebook, they are sorry, because they can do nothing?! The error 411 ist an Error of Sticky Notes?! I thought that an Evernote-Server sends the activation link for my Evernote account. Or is it an Sticky Notes Server? I only want to understand and also it seems that Sticky Notes and the site: http://stickynotes.edo-soft.com/ does not exist anymore. So, by the way, there is also no support to get in contact?!
