Per everything I read on this forum, I decided to do a complete new install. Everything worked except my printers. So I installed Bonjour and when I started it, it did not recognize any of my printers. I checked B4's networking and changed it from NAT to Bridged as Bridged worked for me before. As soon as I said "accept" B4 started to act up and eventually I got the message noted in my PDF. Does anyone have an idea what may have caused the crash? I believe it represents some type of driver issue - but what, I am not certain. Thanks.
