you can disable the firewall if it came with your computer,but even if you disable,it still might not unblock firewall or have you connect,believe me on this,i know,had same problem,i disable firewall,uninstall my antivirus software,did so many things to have firewall unblock and have connection to have all bars instead 1,still never fix nothing till i went to my administrative tool and allow stupid firewall to work with inbound and outbound status,now it works well and now i am having fun listen to my music and downloading it,if you want to try my option,click on my id name and look for my thread that i post,it has instruction how to go to administrative tool,if you do not know where to go ok,i also don't know if windows xp has administrative tool,not sure if all computers has it,but does not hurt to try ok,my pc is windows vista,good luck.
