Troubles with Halion Orchestra

Hi All,

I am de mothballing my brain and Cubase (now Cubase 11) and trying to sort out my plugins, In my plugin in list I have a VST3 called “Symphonic Orchestra” by Steinberg, which I presume is my Halion Orchestra. When I load this into Cubase, it loads fine but the VST will not open the interface. Any ideas people?
