Dynamo Sandbox Graphic issues

Hi there,

I did install Dynamo, I have it as Sandbox and included in Alias.
Both have a graphic issue, no way to see something in the viewport.
I have been looking for some solutions, but nothing changes it.
C++ and DirectX are updated, I added the program to the Nvidia control panel as well

Any idea?
Cheers
