自动升级到4分之3出现一个新的窗口里边显示：
The file "E:gameStarCraft II BetaModsCore.SC2ModBackup.MPQ : VersionsShaders852121baselineCache.bin" could not be written, because an error 2001 occurred. 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.
