I lost my Midi Mapping after closing the app

I spend hours of work to map Traktor S5. After I closed the Djay Pro and reopened it everything was lost. There was no question after hit the close button to save the work.

Hi Manfred Aumann,

we are sorry to hear that.
Could you go to the Midi mapping and see if there is an alternative mapping choosable via the drop down menu?
