Since the switch to iTunes 8, everything (for the most part) has been running smoothly. I’ve been able to create some great playlists using Genius, and I’ve also found some songs that I really like. But then, out of nowhere, I get the following error:

Genius results can’t be updated right now. An unknown error occured (-50).

Please try again later.

Is this just an intermitent problem, possibly caused by a bad network connection, or a problem with Apple servers? Has anyone else encountered this problem?
