Decklink Duo 2 - settings issue

In our studio we have a new PC with a Decklink Duo 2. We used to have an Intensity Pro.

Every time I close Nuendo and reopen it, I have to go to settings / Videoplayer and select the output again, as all previous settings vanish and all formats are per default set as NONE.

Has this something to do with the prefs?


I got that same problem after switching to a Duo 2.
Anyone got one running?
