Can't get Shared to show up on my sidebar in iTunes 11 on Windows 7. Followed all instructions and troubleshooting and nothing is working.

I have just setup my new Apple TV (3rd Gen).

I followed all instructions, have my one and only Apple ID on both my home PC and Apple TV.

Home Sharing has been turned on both devices as well.

The icon shows up on iTunes after I typed in my apple id and password, but after I click Done it disappears.

What can I do?
