Looks like the HTTP server that the appcast was hosted on went down.
A neat trick for open source projects hosted on Github with Sparkle autoupdates - you can use Github Gists for appcast.xml, so it's all hosted on Github. Also provides a nice editor to update it.
An example gist is at https://gist.github.com/joerick/208d698bdab87888f28c, to get the direct link to the XML, append /raw to the URL. Github serves it as MIME text/plain, but Sparkle doesn't mind. Might be useful @mxcl?
I don’t use this app anymore, @MikeMcQuaid was maintaining it but maybe he doesn't want it anymore either?
Yeh, I also don't use this any more. Happy to help debug.
The app's Info.plist is pointed to http://www.methylblue.com/audioscrobbler/appcast.xml, which is @mxcl's domain I think. The host www.methylblue.com isn't resolving at the moment, so that'd be the first thing to fix. Maybe point DNS to an S3 bucket and use the redirection rules to point to something hosted on Github?
I'm still using the app, and I'm happy to help where I can!
