Hi,

KB3133924 isn't an error code but an update specifically this one: https://support.microsoft.com/en-us/kb/3133924

Try downloading it manually using Internet Explorer. You'll find links to the appropriate manual updates in the article. If you have a 32-bit version of Windows 8.1 installed, download the update for x86 based versions otherwise download the x64 version.
