Muse Guitars Vol. 2 — Purchases but MIA! Again.

Muse Guitars Vol. 2 no longer shows in MuseScore 4.4.4's or 4.5's Mixer panel. This happened once before. I don't remember how I resolved it. And it happened again a couple of days, just before the release of MS 4.5.

I contacted MuseHub via their support, but got a generic message with links to various .org forums—implying that this is the best place to get a response.

So I've reluctantly posting here. I've also forwarded a link to this message to MuseHub and requested that MuseHub reply here.
