1st - Did you try off and on again?
I guess, that nobody can read failure notices in German. Did you update your eLicenser software to the latest? What does the eLicenser tell, if you open up it`s panel? Did you try the repair task?
I´m sorry!
This were plugins that came with an audio-unit from steinberg.
I´ve selled it and forgot to de-install these plugins.
After removing everything works fine!
