Strange behavior.
I'm running 8024 Beta as well and I just did a slew of BD9's, no problems whatsoever.
This only occurs with 8024 Beta and BD9, correct?
Firstly, I'd simply reinstall a fresh download of 8024 Beta right on top.
If no dice, use the Fab uninstaller, uninstall Fab, then redownload and do a fresh install.
Be certain to save the installer to your hdd, close, then run as administrator.
Also keep your regkey handy if you have to uninstall/reinstall.
