My Library Does Not Sync (Home Sharing Active), What's Wrong?

Good Evening,

I recently moved and have been attempting to setp up my Home Sharing system which just includes my MacBook Pro, Apple TV, and iPhone (Remote App). All three are connected to the wireless netowork, all three have home sharing turned on, and I disabled by firewall just inclase that was it. Even still, both the iPhone and Apple TV show the message that says I need to turn Home Sharing on my computer. In my iTunes settings, I do have home sharing on and have logged in with the same Apple ID. Does anyone have any suggestions?

Thanks!
