Did you try it with the UAC off ?

What is the Audio set to MME or ASIO, what Midi Synth is it set to in Midi Devices.
Don't give up on it, play around with different settings in Audio Preferences and Midi Devices, you will get it going !

Get off the net and try it with Norton disabled also.

Does it crash when you opened a song that you made in BIAB or without opening any song ?
