Hi Amy.
Have you tryed changing the port numbers to a number between 50000 to
65000, (manual port faward) & (listern on port) should be same number, in
Tools/options/advanced/firewall config. change no's.

PS..I would make kazaa your last resort, I loved kazaa in the early days but it became mostly spam on offer
so if you can find another, I would.
Peace.
