Below you will find several steps to help you resolve the issue you are experiencing.
Remove the retail version of GameGuard
If you’re experiencing errors with GameGuard we recommend you first ensure that you do not have the retail version of GameGuard installed and are only using the integrated version with Blade and Soul. If you’re unsure if you have the additional version installed you can look through your Installed programs list through the Control Panel. If you have GameGuard listed here go ahead and uninstall it.
Delete your GameGuard Files and restart the NCLauncher
First, locate your Blade and Soul folder. By default, Blade and Soul installs to C:\Program Files (x86)\NCSOFT\BnS. Within the Bin folder, there is a sub-directory titled GameGuard. Delete the GameGuard folder and re-launch Blade and Soul. Let it re-download these files, and then launch the game.
Configure your Antivirus/Firewall
If the above does not resolve the issue and the error messages persist, you should verify that you have all firewall or Internet security software disabled. If you are able to connect with your firewall software disabled, then you will need to add exceptions to your firewall rules for the following files:
These files are by default located in the following directories:
For 32-bit versions of Windows:
For 64-bit versions of Windows:
If after trying all of these adjustments the issue still occurs we recommend trying the following steps:
GameGuard errors can sometimes be caused by 3rd party programs interfering with the game client. If you’re experiencing crashing or freezing we recommend you try disabling all 3rd party programs to see if it has any effect on your issue. For instructions on how to do this please reference the KB article here
Sometimes GameGuard errors can be caused by the way your network is configured. If disabling the 3rd party programs and security software was unsuccessful, we recommend you attempt to bypass your router and connect directly to your modem as a temporary troubleshooting step in an effort to rule out potential router problems. To do so please reference our KB article here
Also, please note that you may receive a GameGuard error message if you are running an unverified copy of Windows.
