Hi psalzer,
Let me try to save you from some additional fustration. As you are probably aware of by now, Joker along with a few other european registrars, require that special steps be completed at their site before initiating a registrar transfer in order to transfer your domain to another service.
Go to
https://joker.com/faq/index.php?num=3&f_id=1&s_id=5 and click "How
to Change from joker.com to another Registrar".
It can be quite confusing and you must time your initiation of the transfer request at the gaining registrar within a specific window.
