Halion Sonic SE 2 Preset problem

related to this thread but I did not see this specific issue addressed…

I use cubase pro 8.5 and Halion sonic 2. I’m on a win10 platform. Everything was going fine until last week. I recently did the cubase pro update 8.5.30 but I cannot be sure there is a link, here. The problem started when I got a ‘‘vst library not found’’ in Halion. I am not a pro but I muddled my way out of this. Halion now detects all 3924 vst instruments, I can select categories of instruments and I can see the number of instruments decrease as I refine my selection. But I cannot see any of the actual instruments in the display below. I can see the outline of blank rows but they contain no text.

Of course, I cannot select them so I am dead in the water.

I uninstalled Halion Sonic 2 and reinstalled it: no change.
I keep rescanning the disk: it finds everything but I still cannot see or select them.

Can anyone help me?
