Stop multiple posting and use a real BitTorrent client like Torrent - a (very) tiny BitTorrent client or Vuze: The most powerful bittorrent client in the world.

Stick to one thread I'll be deleting the other posts.

Edit: Might very well be your ISP at fault. Try using RC4 encryption and lazy bitfield settings in a proper client. Limewire's halfassed torrent implementation doesn't include "luxuries" like that.
