That's related to Band-in-a-Box not finding the Sample Tank installation where it is supposed to be, or that your Band-in-a-Box Sample Tank sounds are not where they are supposed to be.

Did you choose a non-default location?

1. The usual location for a key file is:
c:\program files (x86)\IK Multimedia\Sample Tank 2.5\Preferences\ST2Pref.txt

2. If you've got that file, then there is supposed to be a line in that file that tells you where the Instruments are:
ie this line....

InstrumentPath=C:\Program Files (x86)\IK Multimedia\SampleTank 2.5\Instruments\

So that message is telling you that it can't find either that file (St2Pref.txt) or the line in that file. Did you install SampleTank somewhere else?

It likely is a spurious message, if SampleTank sounds are working then it is for sure. If so, just ignore it. I'll surpress that message in future versions of BB, because it isn't needed.

Have Fun!
