File Sharing problems

I've been using Kazaa gold for several years until recently when it refused to connect me to the server. I spoke to a tech at Kazaa gold who was quite helpful but couldn't get the software to work for me. I made sure that my firewall allowed Kazaa and I tried Soul Seek and that program goes into a not-responding mode and I can't seem to get the hang of Bit Torrent at all. I need all the help I can get.
