Please dont tell me to look at another forum. None of them help. Here's whats wrong.

I have dial up. I have had an older version of Limewire for a while now. On Saturday I decided to download the latest version Lime wire. Thats when all the problems started to happen. First, I had to download the latest Java to even get into Limewire. Now I go into it, and it says it cannot connect because there is a firewall or no internet connection. Well, I know that there is an internet connection, because I've been surfing for hours now.
The problem is I DO NOT HAVE A FIREWALL ACTIVATED!!!!! Not any!!! I havent had any problems connecting to Limewire until now, and I havent installed a firewall or changed anything at all!!!! It is very frustrating, and I need Limewire to finish a project before Friday. Someone PLEASE HELP ME!!!
