I haven't run the BS Beta for ages.

But I just installed File_Girl's version & after a while (maybe 5 mins or so during which BS was adding files to my shared Library) found that I had an error from iTunes saying that time & date weren't set correctly.
That's never happened before when running the BS Beta. Never had a problem with time & date.

When I checked in Windows CP (XP) after maybe 10 minutes, the date was still set to 2005.

I've just used RevoUninstaller to remove BS & rebooted, so far all is back to normal.
