J use a program called PeerGuardian when I want to download songs from Limewire.
What it does is loads a whole bunch of IPs mostly bad ones, that want to connect to your computer. And it blocks them.
I had two instances of RIAA trying to connect to my computer while I was downloading songs, and PeerGuardian rejected the connection. Which meant to RIAA that I wasn't even on my computer.

Anyway, the link is www.methlabs.org.

When the site comes up, go to Websites and Projects.
On the left hand column is where you download the PeerGuardian relating to your situation.
I have PeerGuardian v 1.99b pr14 installed as well as the updated blocked IP lists.
I'm running WinXP Home Edition with Service Pack 2.

Anyway, I sure hope this is something you could use.

Bye Bye
