I Having A Problem With Limewire And Firewalls. Can You Help Me With This Window’s Vista Problem?

I’m so frustrated!!! I’m operating on Windows Vista and I have so much trouble running limewire. It seemingly works intermittently with no error message. When I do get an error message it says that there is no active connection or a firewall blocking the connection, even though limewire is allowed through the firewall. So…. I disable the firewall and it still doesn’t work. In addition after that internet explorer will not work until after I enable the firewall again and I restart my computer. How can I get limewire running again?
