Hi,
Most people on these forums -- maybe all -- do not work for Apple or represent it in any way. We are just users liike yourself.
One thing you could try is to contact Apple Support, who may be able to help you. https://www.apple.com/support/itunes/contact/
As regards the Google or feedburner.com forum, you are unlikely to get any help there. You could search their site to see if there is any customer service or help desk.
Before that, try a reinstall of iTunes. First, close down iTunes and uninstall it. To do that, single click on the iTunes icon in your Applications folder to select it -- do not open it. Then go to Finder / File / Get info. At the bottom of the window that appears, you should see something like this.
Make everything Read & Write -- you have to enter your administrator password -- which will allow you to drag the iTunes app from Applications to the Trash.
Now download and install the latest iTunes. http://www.apple.com/itunes/?ref=http://itunes.com
See if that makes a difference.
