It is called "Mittelalterliches Deutschland" - just in case this was not only a typo in your post

By the way: if you ever plan to do a translation in German, we are more than happy to support with proofreading etc.!
(Guess I can also talk for Chris6 in this case...)
And if you ever need a professional translator for such a project, I can bring you in contact with one of our gaming group who does translations for GW-stuff (not part/hobby time - that is his job).
