Simulia CST studio start issue

Hello,

We have an issue creating or opening new project in Simulia CST Studio. When we open the project or make a new one, CST freeze at opening 3D view. It just stops loading that window, look at the picture:


We tried updating graphic card drivers, reinstalled Simulia but nothing helped.
Simulations or schematic view works normal.

What can it be, how to solve this?
