as the title, I open up my download assistant and hit update, then most of the instruments in Halion sonic 3 se were gone.

This is the second time it happened, what’s happening, there’s no halion sonic 3se in download assistant I can just re-download.

Thanks for reply.

I saw this post before,but actually didn’t quite understand thier real solution.

but I look at other VSTi free Navi Harp, i’ve already have it in download assistant, then I found out there’s halion 7, then I uninstalled halion sonic3 and downloaded navi harp, everything just worked, all my halion sounds are back.

I still don’t know what was happening.
