Did you try birdy's suggestions: Did this just start after you upgraded your version of LW? When I upgrade mine I have to make a new exception for LW and when I update java I need to allow it also.

You could try turning your firewall off just long enough to start LW and see if it connects. Then turn your firewall back on. That would help rule in/out your firewall. I don't use the xp firewall so I'm not sure about it, but if your not confident about your router settings I can post some screen shots of how I have mine.

If that fails, try the fixes in this thread: Fixes for Limewire when LW isn't operating as it should!

Oliasys Hi.
I think its your isp Roadrunner, Ive had a few Roadrunner uses with a simila
sounding problem, Phone them, ask if there shaping P2P trafic, if they say No, ask for that in writing. they will come clean then.

Also Vista,L/W & Mcfee working together have ishoos, but can be overcome
Im not up on Vista, so look in the L/W Vista forum, or type Vista/McFee in search. that will bring up other posts dealing with that subject.
Peace.
