I got this message "an unknown error has occurred (12001)" What does that mean? I googled it and found nothing. Please help.
Apple mention some errors in their Help page at http://support.apple.com/kb/TS3297 - expand 'Specific Conditions and Alert Messages: (Mac OS X / Windows)' - but not that one (and the information they do give is a bit vague). I would assume it's another server glitch like '11111' which has been happening intermittently for some time. I'm afraid that probably all you can do it try again later - you could try emailing them at podcasts 'at' apple.com but I can't promise you'll get a helpful answer.
