Halion Symphonic Orchestra - program always loads default

Hello all-

Running a very old version of HSO that I haven’t used in a few years, but today when trying to add it as an instrument in Cubase 4, or with the stand-alone player, I can’t load any of the programs included in the .hsb files.

I have validated my license is active and working in the eLicenser. I have made sure the .hsb files are properly located and selected and opened. All program banks/instruments appear in the list. However, when I select a program for a midi channel, the selection changes to default. This happens for all channels.

Wondering if anyone can shed some light on this problem?

Thanks in advance!
