I have successfully fix the problem in µTorrent.
When you open the torrent tracker, they will ask you "Save In" which you should give your path. Then they also ask "Name" which should be the folder name. So what you should do is to put <my path>\EA GAMES\ in the "Save In" box. Then put "Battlefield 2" in the "Name" box. It will check all the available files, and voila, you will be seeding very soon.
Currently seeding at 200 kbps+
