Online now icons not working...

The online now icons never display when I'm logged onto myspace from my computer at home. Actually, when the code to change someone's online now status was working, that was the first time I was actually able to see people's online now status from my computer in months. But that was short lived. Anyone have any ideas why they don't work? They don't display in IE or mozilla, even with my antivirus security and adblocker turned off. I am on an older machine running windows 2000 professional, which I'm wondering if that has something to do with it. Because if I log in on a friend's computer or at work they display fine...
