When i do my setup dialog thing, it just ends where it says i should unblock it, But its already under my trusted sites. what else do i have to do?

You have to allow Limewire access to the internet if you have firewalls running. What firewalls do you have? Have you configured them to allow LW access? You should only have one firewall running, by the way, so if you have Windows and some other security suite, I would turn one firewall off (Windows XP and Vista have firewalls).

i have xp, and my anti virus is trend pc-cillian, i shut off the firewall and tried it again, but it still jsut ends at the same part that tells me to allow limewire.

Try port-forwarding for PC-Cillin:
