Whenever I try to install wow I get this error
"An error was detected while verifying the contents of the file "C:\World of Warcraft\Data\common.MPQ". There may be a problem with your system, or with the drive at C:\. You can attempt to install again. If this problem persists, please contact Blizzard Technical Support"
This is the downloaded version from the Blizzard website by the way. How do I fix this? Thanks.
