An error was detected while verifying the contents of the file "C:\Users\Public\Games\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.
Any suggestions what to do?
I run on Windows 7 Ultimate.
