My existing license does not work anymore!

Users usually get an error message like:

"The license you have submitted is invalid. Your license has not been updated."

Since release 1.5.1 our licensing is done via Atlassian Marketplace - this requires a new license format. Recently we sent a mail with the new licenses to all customers of our plugin. Please enter this license after you upgraded to release 1.5.1 or higher. A more detailed description is available in the /wiki/spaces/upp/pages/9405814. If you havn't got a new license please contact us via confluence-support@communardo.de - we will create a new license for you.

P.S. A more general Marketplace FAQ is available in the Atlassian documentation.
