First, Let me get the important information out there.
1.Windows XP
2.Norton (I have the firewall turned off!)
3.Lots of Ram and Disc Space
4. Broadband
5.Connecting from Home
6.Limewire 4.13.6
7.Local ISP-Wireless Connection
8.When I try to go to http://www3.limewire.com:6346/ , I get a " Firefox can't find the server at www3.limewire.com."
9.I had Limewire Pro once but not now. I used to have no problems downloading but now...nothing
10. I have the brick wall indicating firewall

Ok, I get great search results but when I try to download something with a lot of results, It will say "connecting(## Hosts Tried)...
What does this mean?
Thanks for any help you can give me!

Are you running on a Linksys router? If so I have the same problem.
But my issue is the newer versions of the WRT54G models (Above v5) can't handle multiple source downloading from what I understand. The router chokes when you try and download from too many people. + My bittorrent download speed has drastically dropped from like 800kb/s to 200kb/s for single torrents. I really hope they fix this with a new firmware upgrade.

I'll be honest, I don't know what kind of router I am using but I do believe that might be the problem.
