Hi Matt,
They're working fine for me (this video shows that
http://screencast.com/t/5elSUnzmHFor pushes to work, you need to have the holds installed. They use holds 272 and 274, so you'd need to have folders:
C:\bb\RealTracks\Library\Holds\Holds_272
C:\bb\RealTracks\Library\Holds\Holds_274
So you should check that holds work, and if they don't, see if you have those holds folders. If you don't, then your c:\bb\default.sol isn't current, because it is the "soloists file" that points to them.
