I have installed Materials Studio 8.0 on Windows10. There were no errors during installation. When I tried to use Dmol3 to do some calculations (Modules -> Dmol3 -> Calculation), error message which said "Unable to connect dialog" showed up.

Then I clicked Job control, there were no server gateways registered. 

After I closed Dmol3 panel, I got "OnDisconect"


Other modules all works well, how to deal with this?
