Configuring firewall/compatibility?

[Airhorn_Girl]

Is it possible or do I NEED to configure Limewire in some way to work with my Vista or something because when I had an XP I never had any trouble whatsoever with Limewire but now that I have a Vista sometimes (okay, a lot of times) when I open Limewire and get a song(s) downloading, they will not get above 3-5kb download speed and I see no reason for this to happen. I've tried going to the settings/preferences and tweaking them around but nothing has helped. I don't know what to do but it's driven me to the point where I've had to try out different downloading programs because there's nothing I can do. I don't want to have to do that because I hate all the other downloading programs, they suck. I'm used to Limewire so I don't want to give it up.

I have Cable, for reference.
