Bonjour not working in PC?

A few months ago I received an error code from iTunes saying that "The Bonjour had been disabled....." and I didn't pay much attention because iTunes was working perfectly fine. I just bought myself a new Mac Book Air and since it has no CD drive I wanted to Homeshare my music files from my PC to my Mac.

I turned on the feature from both computers and they wouldn't appear on my iTunes menu. I went back to my iTunes on PC went to Preferences and finally sharing. There it has the same message from above. I went to my services to "re-enable" Bonjour but it says it's running. Yet, iTunes stills says it's not. I've tried repairing from Control Panel but the problem still remains. I really don't know if the firewall has to do with it, but I turned it off and it still doesn't work.

Do I have to reinstall iTunes all over again? Or is there an easier way for me to transfer my music to my Mac? Like a USB drive perhaps? I would really try to fix this problem. Please help! Thanks.

My old PC is a Windows 7 by the way.
