Frostwolf Wont Lauch

So I spent hours looking through forum posts etc but couldn't find anything.
I have the config.wtf file set to:

SET realmlist "logon.warmane.com"
SET locale "enGB"
SET installLocale "enGB"

But whenever I try to launch the game I get this error

Close ur bittorrent program
Move the folde aways from the downloaded location
Go into ur WoW 5.4.8 folder, rightclick on ur WoW.exe. properties, and then uncheck "read only"
