Wiz,
Sorry to read that you are still having problems.
When I go to rebuild the styles, BIAB beachballs and I have to force quit
To me it appears that your MacOS as well as your MacBand's Audiophile USB needs to be repaired.
Try running Apple's Disk Utility on that Audiophile USB.
And also Start up in safe mode ( holding shift key while doing a restart ). If you are not familiar with that process then when you are in the finder ( click the desktop ) go to Help in the Apple menu bar and type in Safe Boot. That will provide you with an explanation and details as how to.
