One more thing....

I don't know what I did but I tried restarting my computer again and is strated working again! (this was about 2 hours ago) and I downloaded 3 more songs with no problems and then it stopped working again and it is back to how it was and I didnt even change anything! (Also, the firewall symbol in the corner was still there when I was downloading and is still there now that it isnt working again)

I'm really desperate---- Please help! THANKS!
