There is a menu that is called "Plugin information" or something like that. Find it and see if BFD is installed there. It's possible that it is not active and you just need to reset your plugins. If it isn't there, something bigger is going on.the only options I get for adding and instrument track is either "no vst instrument" or "HALionone"
I'm surprised that Halion One is the only VST instrument you have. You don't have any of the "LM" plugins that have came with Cubase for years?
