On the one where you are at 99.7%, did you have a text file open from the torrent when you started seeding and closed it and saved the changes? If so then it will be modified and you won't be able to complete seeding. The audio files might be OK though. Until you get it fixed or start a new torrent, you could tell the people waiting to test their audio files and see if they verify. Don't worry, someone will help you get the problem sorted out.
