One of my Bittorrent downloads has stopped working. I know my internet connection is fine, and one of my other torrents is uploading just fine, so I know it isn't Bittorrent's connection that isn't working. It was downloading only about half an hour ago, when my computer had a (non-Bittorrent-related) error and restarted. Now that one download won't work. It even shows that there are other seeders, it just won't connect to them.
