Data//wow-update-base-18273.mpq. World of Warcraft can't make a required change to an archive file. Be sure you have write permissions for the World of Warcraft folder or try running the game in administrator mode.
I've tried running as Admin, Disabled my AV and i've checked the Security Permissions to the folder and even went as far as to set it to 'Everyone' with 'full access' but it still fails. I would rather not have to re-download the client, so any suggestions would be most welcome.
