Cubase Doesn't load

Hello, I have just purchased the new Cubase le 10 and it is acting very weird. The installation and authentication went smoothly up to the moment I’m ready to open the program for the first time and my mac(Sierra) freeze and just show a black rectangle. I tried to reinstall but it happened the same identical problem. Any idea?

Hi and welcome,

Can you see the Splash screen while booting Cubase? Can you see the Steinberg Hub after? Could you attach a screenshot, please?
