Bad buss - crashes Ableton Live 8.1

Any news on this issue? I’m on 10.5.8, Live 8.1 and I downloaded the latest version (I’m using AU). Still wiping out Live whenever I try to insert it. BBM is gorgeous and I must have it working again on my system!

I’m still getting the prompt screen too, despite paying, but saw a post on this in a separate thread, so will investigate later.
