Can't Log in into game server

I played wow(MoP) 3 days ago. And I can still log in website and can't log in game server. I got error message like this "Data/enGB/wow-update-enGB-18273.MPQ: World of Warcraft can’t make a required change to an archive file." I have tried every possible ways to fix this error.

have you tried this already?
Follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"

Yes already did
