Well, if you want people to help you then first you need to help them. I can't read your mind and (always) understand your problem.
First, how do you connect to the internet? Do you have regular ol' dialup (I bet you don't!) Do you have cable or DSL where you plug your network card into a DSL modem? Are you on a home network all connected to the internet through a router or firewall? These are very important questions in helping me diagnose your problem.
