Have you done a test of your Nat/Firewall settings?
You may have your receive ports blocked?
In advanced network settings, do you have
bind to local IP? Are you running an AV or Malware?
Have you allowed Vuze through your firewall?
If you have a router, have you allowed the listening
port access in it?

I know it's a lot of questions but hard to help without
you try a few of these first.
