evernote desktop authentication token expired

When trying to activate my user account again by clicking on the Request activation link button, the dreaded “The remote server returned an error: (411) Length Required” error message came up. I have tried removing my Evernote user account in the settings menu of the Evernote Sticky Notes application in order to fix the issue. The Error code was: AUTH_EXPIRED, Parameter: authenticationToken. To move your key to production please request your API key be activated on production.A week ago I started getting Synchronization Failed error messages in Evernote Sticky Notes for Windows, which meant my Sticky Notes stopped being synced to Evernote server and consequently across all of my devices.

Using the value of oauth_token above (it should start with the form S=s432:U=4a535ee:E=154d.) you can now make requests to the API on behalf of the user that approved your application! You can use this token to perform actions in Evernote like saving content and data to notes and notebooks and (if your API key has the permission to do so) reading notes, notebooks, tags, performing searches and retrieving business data for use in your application. The value of this parameter will be a standard UNIX timestamp in units of milliseconds indicating the date and time of expiration. In all these cases (including tokens valid for 1 year), the expiration date will be included as the parameter edam_expires. The user can alter this duration to 1 day, 1 week or 1 month. By default, the duration of access token validity is 1 year from the date of issue. Each access token has an expiration date.
