black sky with VRi CDU II

Hey folks,

I have a particular problem with my new VRi CDU II and AS2012.

Option 1: I start the CDU II and the VRiSim Software before I start AS2012, then this results in having the sky black. But not at every angle of view, when I look to the left everthing seems to bee fine, but straight ahead and to the right, the sky is black. I can see clouds though.

Option 2: I start AS2012 first and the the CDU II with its software, then this results in the CDU screen remaining black. No problem with the weather or sky in this case, but I cannot use the CDU.

Does anyone has an idea? I'm happy for every suggestion.
