RSS Feeds in Mail - error -

Hello,

Please help, my RSS feeds in mail and safari will now not work ?!?!? I can this error in Mail when trying to update a feed :

There was an error updating the RSS feed “Apple Hot News”
An error internal to the Publication Subscription framework occurred.

And when I try to view it in Safari I get this :

Safari can’t open the page.
Safari can’t open the page “feed://images.apple.com/main/rss/hotnews/hotnews.rss”. The error was: “Operation could not be completed. (PubSub error 203.)” (PubSub:203) Please choose Report Bugs to Apple from the Safari menu, note the error number, and describe what you did before you saw this message.

I was wondering if anyone has a solution to this issue, as RSS feeds are crucial to me ????

Thanks

Joel
