Thanks Jim, I will pass this along and then move to the other forum. I installed the update... no change. Triple checked the drive and folder and everything is set to install/run from the G:/bb/ folder.

This is the yellow box error I get when I try to apply one of the styles:
RealTracks not found: (Style) (Set #123) 1412 Guitar, Acoustic, Rhythm CelticHornpipe Sw16 070, [2021.822.0, 2/22/2021 6:33:49 PM]

So, if everything is pointing to right folder (G:) I must not have these RTs installed. Don't the instrument tracks come with the program or the styles?
