I’m afraid that this sounds like database corruption. The cause of this is unknown to us at this point. Vienna’s database is located at “~/Library/Application Support/Vienna.messages.db”. If you backup your home folder frequently (which everyone should), then you can quit Vienna, delete “messages.db”, and replace it with a recent backup. If you don’t have a backup, there may also be a file “messages.db.bak” in the same folder; check the last modification date on that, and if it’s recent enough, then you can quit Vienna, delete messages.db, and remove the “.bak” extension to use your old database.

If you don’t have either of those things, then you still should be able to export your subscriptions and re-import them. Export all of your subscriptions, quit Vienna, move “messages.db” to a different folder, and re-launch Vienna. That will create a fresh database, and then you can import your subscriptions again.

Oh bother… Guess my Vienna database is corrupted. And I’m not one of those smart people making regular back ups of their home directory either.

This could be a blessing in disguise since I was not being able to keep up with my reading. I’ll take some time to clean out my messy RSS repository and start over. No doubt there will be a number of gems to links to…

That’s it. I give up. I have tried to understand the way NewsGator syncs its products and get it to work for me. In the process I’ve lost over 6,000 feed items and many hours attempting to retrieve them. Was it too good to be true? All I wanted was a reliable system to sync feeds on different computers across platforms. The applications themselves are fine—it’s just the feed synchronisation I ran into trouble with.
