I cannot suggest torrent sites because it would sort of go against our forum rules. However, I suggest you google such. There's plenty out there. There's also private ones however most private torrent sites do not allow LimeWire. Decent Torrent programs are Bittorrent & Azureus (Vuse).

The greater download % you get with torrents the slower they tend to get since they rely upon partial file sharing. Thus you are downloading the file at same time as others & they are uploading what they are downloading. So depends on when the people with the entire file are online. Patience is best.
