The danish text "Værdien falder ikke inden for det forventede område." means something like: "The value isn't within the expected area". And "Objektreferencen er ikke indstillet til en forekomst af et objekt." means something like: "The object reference can't handle an instance of an object".
So if you have the MOD and use it, then please de-activate the "No Mouse Over Sound (Stridor)" until we have a fix.
