You will not get banned for any of these messages. They also do not mean that SmartGuard is searching through files on your system that are not related to the game. The message means the game process tried to load this file, that is the reason it is being checked.


If these messages do not cause problems with the game, you can just ignore them. Protection can be quite strict, which can lead to blocking of certain files that are not essential for the game.

If the game still does not run, try this list of possible solutions:

  • Scan your system with latest antivirus software. Malware that modifies system or game files, can cause such problems.

  • Make sure you are not using modified system files (e.g.: custom Windows themes or DirectX). Reinstall DirectX, see the following page for more information:
  • Proxy programs and other similar software (such as adware) that intercept all network connections in the system may be incompatible with SmartGuard. Their removal and TCP/IP reset may be required for game to run correctly. Uninstall this software, if this does not help follow a guide from Microsoft:
