When I open the hub, the tabs at the bottom are not working (Create/Create Empty, etc), there is no way to close the Hub, the text and graphics are a bit blurred. This is after a new install. Windows 8.1.
Hi and welcome,
To me it looks like there is another window opened, probably hidden behind the Hub. Could you check in the Start bar, how many (and what) windows are opened with Cubase, please?
