i downloaded the basic version of Limewire (free) to give it a shot and see if i like it. it downloaded fine and i went through some firewall instructions to allow limewire to access the internet from my computer. when i try to download a song it says "needs more sources." afterwards, a message comes up saying that my filter is still on. i am running mcafee, and i dont know what else to do. can someone help me? ****
