i can only see computer and settings on my apple tv (3rd ed). how can i get netflix?

Hi all,

I just purchased a 3rd generation Apple TV (very exciting). I was able to connect to my wireless connection. However, at the home page I am only able to see computer and settings. When I try and connect to establish a Home Share, I get a error 3259 (can't connect to the server) message. Any help would be greatly appreciated.

Thanks.
