Generally the best thing to do with torrents is have patience.
Unfortunately LW does not show how much of the file the other sharers have. So .. the two hosts may in fact have the same amount as you or even less & perhaps like you they are awaiting for someone to come online with a larger % or full content of the file or parts of the file they & you don't have. This is not an uncommon scenario with public torrents, especially older ones.

There's always the chance one/both of the hosts has banned your host but that's only a small possibility.

With Vuse (Azureus), I can check how much of the file each of the other hosts have, which parts of the file they have & I don't & vice versa. I can also prioritize particular parts of the file. These things are not possible with LW.

(I retitled the thread to show the discussion is about torrents.)
