I get the same error in build 291 and now it continues into build 292. I have a totally up to date computer (Intel Dual Processor, 4GB RAM. 1 TB hard drive, 800 Mb front bus) and work in the computer field building these so I know it's not something where the hardware is lacking. It only seems to happen when I am working with some of my older songs from previous versions (2007 and 2008)

I use Reason 3, Acid Pro 6 and Sonar 8.5 and they all run flawlessly on my machine so it has to be something with BIAB 2010. Mostly in relation to whenever Real Instruments and Real Drums are introduced into the song.

Sometimes the song will just crash with the following error message "Access Violation at Address 006C3E99 in module bbw.exe write of address 00011110 at; 006C3E99"

Sometimes it's a message where it fails to recognize the ASIO driver from my M-Audio Fast Pro and even restarting doesn't do much.

I think that at this time although the update to BIAB 2010 is awesome, things are still at a very glitchy stage.

Hopefully some update patches will resolve these problems
