Looks like you're on PinballX V6.02 so you may as well update to the latest version.
After the update can you post pinballx log files after the issue for the regular VP system for Big Bang Bar and for the 3D system so they can be compared (might be different issues). Ideally open a 'working' table in the VP system that exits normally before opening and attempting to exit Big Bang Bar so that is in the log too.
When the hang occurs, is VPX still open or does it fully exit (with no left over visual pinball processes in task manager [details tab])?
