Problems opening Cubase Pro 9.5.10 on Windows 10

I’ve now upgraded my graphics to NVIDIA Gefore GT 710 and also got a new audio Interface, US-Tascam 16x08. Nothing has helped regarding Cubase. I even tried installed Cubase 8.5 Pro which suprpringsingly acts the same, hangs within 60 seconds.

No response from the support (it’s been two weeks now). I’m gonna overlook that fact for a while longer since it’s been holidays and stuff so I’m thinking it’s been slightly understaffed but I need some pro advice.
