VST Connect Pro 3 - Can't open edit window?

I’m currently trying to get VST Connect Pro 3 working in Cubase 8.5.

In a Cubase project, when I head to VST Connect > Pro > Create VST Connect Pro, a performer track is inserted, and everything seems to work normally - however the editor window (with the mixer, performer window, connection settings, etc) doesn’t show up.

The option to ‘Open VST Connect Editor’ in the VST Connect menu is also greyed out, and I cannot select it. The same goes for the ‘Open performer video’ menu item.

I have the latest version of both Cubase 8.5 (8.5.20), and VST Connect Pro 3 (3.0.100).
I’ve also tried running Cubase in safe mode with no success.

What’s going on here?

I assume the “Open VST Connect Editor” is disabled because the VST Connect Editor Window is already open. Check to see if it vanished behind other Cubase windows. See if you can select it from the taskbar. That behaviour may depend on how plugin windows open (e.g. “Always on top” disabled).
