I didn't use ASIO drivers for years, but I do for some things now. I used to get access violations (don't remember the addresses). What was causing mine was the popup windows that came when I rendered via the render window which is now in the audio menu. There are 2 windows that caused me trouble. They were behind the main biab screen window. Tech support suggested that I make the main screen window smaller so that I could close those windows after rendering and before I closed the Biab program. That solution worked. Don't know if this helps or not. Good luck!
