Seasons greetings.

I bought Band In A Box 2020 pro version today and installed it along with the Pro RealTracks 1 to 6.

I also bought RealTracks set 349 with a view to creating some fiddle backing tracks that sounded like this (using my own chord sequences):



However when I installed it and tried to load a style from set# RT 349 I get this bunch of errors:



What am I doing wrong here? Do I need to buy yet more stuff to get it to work?

Thanks in advance.
