Problem with utorrent... Need help!!

[Laverius]

I've got a problem with my utorrent.. I've started downloading a movie using my friends wi-fi connection and it was all OK (downloaded ~50%). Then I've came to my library, connected there and utorrent downloaded another 50%. And now when I try to start new download, it doesn't start.. Any suggestions?

What exactly does it say or show up as? There can be many reasons to this. Broken tracker, bad connection, closed ports, very little seeders etc.
