Apple TV can not connect to Library
After updating my Apple TV 2 software to the latest version the other day I have been unable to connect to my library. After a period trying to connect the Apple TV displays the message ' Could not connect to "xxxx's Library"'. I did have trouble with the update, it failed wirelessly but was then able to update using USB. The network connection and internet access is fine and I have tried resetting/rebooting/switching everything I can find that is associated with it to no avail. Additionally, I have noticed that the white status LED no longer illuminates (also since the update).
System info as follows:
2.4GHz Intel Core 2 Duo MacBook with OS X 10.5.8
iTunes 10.5
Apple TV Software 4.4
Thanks in advance for any help or suggestions.
