A few suggestions:
When it crashes, does it produce a crash report file that you could attached to an email and send to PG Music Support?

The problem may be ASIO related, as you have suggested. Try setting the Audio Driver Settings default to MME or WAS, and restarting BiaB.

Try returning to Factory Settings (Options menu).
