I try to turn Home Sharing back on and it Accesses iTunes Store Forever

My Apple TV was using home sharing perfectly fine. At some point my home computer simply stopped showing up. I tried rebooting it and my computer and nothing made it show up. I then tried turning off Home Sharing with the intent of turning it back on again. I put in my password, hit the button and it just goes to "Accessing iTunes Store..." forever. It never turns it on successfully. Now I can't stream anything. I also tried uninstalling and re-installing the latest iTunes but I get the same result.

Help!

Thanks,

Darryl
