While most video game players are happy when developers implement anti cheating software, they become frustrated when that software malfunctions and interferes with game play. GameGuard is used by MMO developers in many Windows-compatible games to detect hackers and bots. It is often troubled with update and loading errors that can prevent subscribers from logging in. Here's how to update GameGuard so you can get back into the game of your choice.
Disable your firewall. You may need to do this whenever you play the game protected by GameGuard in order to prevent a GameGuard error. If this is the case, configure your firewall with an exception for the game client instead of disabling it completely.
Remove the proxy server option from your LAN settings. This in the "Internet Options" section of the Control Panel.
Run antivirus scanners and update or remove malware as needed if your GameGuard error indicates an infection. Viruses can affect how GameGuard connects to its host server and whether it is able to update GameGuard automatically.
Launch your game client by choosing to "Run as Administrator" from the right-click shortcut menu. Not having administrative rights on your computer can prevent GameGuard's access request from initializing. If you never get the access request, you can't approve it and the automatic service to update GameGuard will not launch.
Update DirectX. You can check to see if you have the most recent version by visiting http://www.microsoft.com/downloads/en/details.aspx?familyid=2da43d38-db71-4c1b-bc6a-9b6652cd92a3 and comparing the DirectX version to that installed on your computer. See which version of DirectX is installed by running the dxdiag.exe program.
Check to be sure you have the most current driver for your graphics card. Visit the website for your graphic card's brand and search for drivers for your graphics card. Alternatively, you can use the Device Manager in the Control Panel to check for updated drivers.
Try logging into your game during off-peak hours. The GameGuard servers may simply be overloaded, especially following a large GameGuard patch.
Uninstall and reinstall the game that uses GameGuard. This should only be done when the GameGuard installation proves to be corrupt through display of the error. Make sure to back up your personal game folders before uninstalling and reinstalling, so you can copy back any personalized settings, key binds or macros.
