Can't get MonoTorrent to download

[hexafluoride]

I'm trying to download some files and both with the SampleClient, and using the code below, it always stays at Downloading, and 0 percent.
I've tried downloading various torrents including Linux distros.

What could cause this?

Console.WriteLine("Torrent test...");
Torrent t = Torrent.Load("/path/to/torrent");
TorrentSettings s = new TorrentSettings();
s.MaxConnections = 100;
s.InitialSeedingEnabled = true;
s.MaxDownloadSpeed = 500;
s.MaxUploadSpeed = 100;
s.UploadSlots = 4;
s.EnablePeerExchange = true;
s.UseDht = true;
TorrentManager tm = new TorrentManager(t, "/path/to/save/location", s);
EngineSettings es = new EngineSettings();
es.AllowedEncryption = EncryptionTypes.All;
es.ListenPort = 22239; // forwarded, both UDP and TCP
es.PreferEncryption = true;

ClientEngine engine = new ClientEngine(es);
engine.Register(tm);
tm.Start();
Console.WriteLine(engine.IsRunning); // outputs True
while (true)
{
    Console.WriteLine(tm.State.ToString() + ", " + tm.Progress); // just keeps outputting "Downloading, 0"
    System.Threading.Thread.Sleep(1000);
}

Try putting break points in these key places and see if the code is getting hit :

TrackerManager.Announce << did it even try to announce
TrackerManager.OnAnnounceComplete << did the announce go through
SocketListener.EndAccept << anyone try to connect to you
ConnectionManager.ConnectToPeer << did you try to connect to anyone else

My guess is that your announce is getting blocked or not returning any peers. See if you get any peers back in OnAnnounceComplete.

Never mind, it eventually finds some peers, it just takes a long time on some torrents for some reason.
Seems to be random behavior too.
