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.
