If you want to dload ROTK using bittorent do this:
Go to google and type:
The.Lord.Of.The.Rings.Return.Of.The.King.SCREENER-RING
google will then bring up 3 sites.
The one you want is
BitTorrent @ TLF
bt2.eastgame.net/
instead of clicking on the name of this site click on the gray underlined word Cached to the right and it will take you directly to the file (it will be highlighted) then just click on it and get your file!
P.S. this site is in chinese but if you follow these directions you shouldn't have to download the language pack.
Enjoy!
