beta旧的客户端已经无法升级？

我更新beta文件， 却出现如下出错提示：

The file "E:StarCraft 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.
