VST connect pro freezes Nuendo when loads

Just upgraded to Nuendo 13. First bug:
VST Connect Pro 5.6 hangs the Nuendo app when I call it to load. Just freezes the computer. Happening in all sessions including a completely fresh/blank one with no plugins at all.
Everything is updated to latest version and eveything is activated.
Re-installed several times. Nothing better. Re activated several times. Nup.
I can make work VST Connect SE, but not the Pro.
Any ideas?
