Hi Paul,

No, we haven't seen any problem like that before.
BB 2009 does work with 10.4.x and higher.

The message indicates that the "bt0" file, which is present in the RealTracks folders, are not able to be loaded properly.
Possible causes:

- Network permissions - you should have full "admin" permissions, not limited
- Antivirus program interferring
- Case sensitive file system set (that is an unusual setting that some people make, that makes their whole Mac file system case sensitive)


Q. Could you give us the full message that appears, it should say "Error: CalcBeatAryAndSaveBT0 " and also say the filename that couldn't be loaded. Does yours just show Error: CalcBeatAryAndSaveBT0 and nothing else?

Q. Every real tracks, for example on the demo song =George_P.MGU


Have Fun!
