Does the freeze occur after you hit Play, or while you are typing in the different chord?

If the problem seems to be related to the change in audio driver, then you might want to try running Band-in-a-Box with factory settings. The best way to do this is:

1. Restart the computer.

2. Before opening Band-in-a-Box, open it's directory (usually "C:\bb\") and move this file out of the directory:

intrface.bbw

3. Open Band-in-a-Box, and it should be set to use MME drivers with the default factory settings.

If that does not help and you want your old settings back, you can repeat these steps but put the "intrface.bbw" file back in the "bb" directory.
