SIQ, VST 1.11.7 and Cubase 9.5; can't get it working ... Anybody?

Just sent to PG support:
---------------------------------------------------------------------------------------
installed 1.11.7 after deleting all the old versions (manually according your list).
Cubase 9.5.41, Widows 10 64bit, RME UFX ii, ASIO.
Biab 607 plays well with a latency of only 128 samples, no distortion it seems.

Plugin loads, only on a Cubase 'intrument'= VST track, has to be seen as VST.
Plugins like EZdrummer can be addressed via a 'normal' MIDI track.
checked the RT locations in preferences etc, but as soon as i address and load a MGU songfile, the plugin disappears, and when you bring it up front again,
you get this page (again, as with the old version). (SEE PICTURE)
OK this and the plugin is up front again, it loads a selected style, but the tracks won't be rendered.
(pressing select style goes to the correct folder, pressing demo produces sound from the VST.)

ADDED information: I just loaded an old SGU MIDI only file OK, plays etc, seems the audio-RT stuff has a problem ...
