Can you please provide more details on your system and the steps you took that lead to this error message. Please refer to this page for guidance.
Right, sorry about that.
I'm running Adobe Premiere CC with the latest updates installed
On a MacBook Pro running version 10.8.4
The issue occured when making a specific edit and would crash when attenpting that edit - every time. I was dragging media back to fill in a gap in my sequence. The problem went away when I unlocked the audio tracks. Seems strange that the crash would be so specific.
