"Leechers" are people like you, who don't have a full copy yet... they can share what they have with you, but if there's not at least one "seeder", then eventually you will all have the same amount of information, and transfers will cease until someone with the entire torrent connects again (if they do). Do make sure you wait at least 10-20 mins before discarding a torrent, though, as sometimes it takes awhile for you to find all of the seeders / leechers. If there are no seeders, then ditch it. BTW, have you at least
tried the SCP torrent in my sig? (hip63's one) I absolutely positively know that one works,
because I'm seeding it 24/7!
If it doesn't, then you have a problem with your connection... visit
www.portforward.com with your router make / model # handy, and look for how to 1) set up a static IP
with your router, not your ISP, and also how to forward your port.
