could you pls kindly help me when I update my client from 22.214.171.12405-3.3.0
Blizzard Updater was unable to read the file "D:\Program Files\WOW\World of Warcraft\Data\enUS\backup-enUS.MPQ". This error may be caused by problems with the media or drive at D:\--for example, a scratched or dirty CD-ROM/DVD-ROM, hard drive corruption, or a networking problem while downloading the update. (The data being read was "msvcr80.dll", and the error code was 0.) If this problem persists, you may be able to solve it by uninstalling and then reinstalling the game. If you are unable to correct this problem, please contact Blizzard Technical Support. (Converter::Load)
