With torrents it's usually a case of wait and see. If it's an old torrent then less chances of getting more hosts. Keep in mind people come & go offline at different times of day so that is a hint.

BTW not all other torrent programs accept connecting with LW. And some users have their programs set with high preliminary requirements to connect to them such as a very high share ratio. AFAIK LW does not show you what your share ratio is.

Personally I use Azareus for torrents.
