1. Ensure that your Internet connection cables are secure. The GameGuard error occurs when the software cannot download needed updates. Unconnected Internet connection cables could be the cause. If it is not, proceed to the next step.
2. Click the Windows 'Start' button, the 'Control Panel' option, then the 'System and Security' option.

3. Open 'Windows Firewall.' If a threat is detected, the firewall prevents the program from accessing the Internet, but sometimes the firewall blocks programs that are not threatening, such as GameGuard. Disable the firewall by clicking 'Turn Windows Firewall on or off' and selecting 'Turn off Windows Firewall' under both the public and private network headings. Click the 'OK' button to save recent changes.
4. Allow GameGuard to update, then return to the Windows Firewall menu and enable the firewall again. The error 380 should now be eliminated.
