I use this version to play on Gameranger / Hamachi / Network and suggest everyone do the same thing. Next download Gameranger and play with your friends online. All you need to download and install Special Edition. You dont need to crack or patch the game to play online with other players. If you ask me that what is special edition, I would say best version of RoTWK with new game musics (also you need to install BFME2 Special Edition ) 'The Lord of The Rings Soundtracks', new images, and much more features (read all features below). If you play with this edition vs someone who doesnt have, NO MISMATCH PROBLEM. This is The Rise of The Witch-King Special Edition.
