Here is what it going on:

First off im using windows XP. The first day i downloaded Limewire, it worked; i was able to download three files. I started downloading another two and they got to 81% and 21%. after that it couldn't find any sources. also every few seconds the connection would disconnect. It says im behind a firewall but when i check it, my computer would say that its not able to start a firewall. My searching problems are also annoying. I would try to search for something and no results shows up. I've tried deleting the preferences folder(didn't work), tried updating java offline (didn't work), turning off tips(didn't work), turning off autoconnect(didn't work) and thats about it. can anyone help me. its starting to get really annoying.
