Setting up Jitsi Videobridge

Hi all,

I've downloaded Jitsi and have successfully had an encrypted text chat over facebook. I noticed though, that I couldn't video call using just this method so I downloaded Jitsi Videobridge. I extracted the folder and ran the .bat file, but I still can't set up video conferencing (it's still greyed out in the Jitsi "tools" menu. If anyone else has experience with this perhaps you could help me out?
