While trying to work along with the YouTube video:
"Band-in-a-Box® 2019 VST DAW Plugin for Windows®, demonstrated in Reaper®"
using 2021 UltraPak, I double-clicked _CROONR1 from the Style Picker but got an error that it couldn't find the Style Demo Audio _CROONR1.wma. The specific error:

Miscellaneous Error playing M:\BB\REALTRACKS\Data\Style Demos Audio\_CROONR1.wma. Windows Media Player cannot find the file. If you are trying to play, burn or sync an item that is in your library, the item might point to a file that has been moved, ren...

I checked the directory, found the _CROONR1.wma file (and can play it with Windows Media Player & VLC). The style can be loaded and used but BIAB can't seem to find/play the audio file to play in the 32 bit or 64 bit versions or the DAW plugin. My BB\RealTracks and BB\Drums folders are stored on my NAS with a mapped drive M: (pref folders set to M:\BB\RealTracks\ & M:\BB\Drums\ ).

Any ideas?
