Does the error message look like this? Does the message disappear if you click [OK]?

That error message shouldn't appear if you have the Show Warning for Untested Soundcard Formats setting unchecked.
If you can get Band-in-a-Box to run, go to Options > Preferences, Audio, Audio Drivers... to change that setting. Or return to factory settings because that setting defaults to off.
