I've downloaded Mists of Pandaria and it does not work.

Whenever I try opening the game I get the following error message :

Data/enGB/wow-update-enGB-18273.MPQ: World of Warcraft can’t make a required change to an archive file. Be sure you have write permission for the World of Warcraft folder or try running the game in administrator mode. For more information, see: https://battle.net/support/article/6910

Please tell me I haven't waited for 2 day for this not to work, I am pissed of to say the least.
