Be sure you have write premission for the World of Warcraft folder or try running game in administrator mode. For more info : blablabla" . Did try to run it as administrator got same msg,any help?

Right click on the root folder (the one in which data, cache and WTF folders are), and change it from read only. It would help to move it from where the torrent has stored it, as sometimes the torrent tool can change it back to read only.
