First, make sure your computer meets the minimum system requirements to run the game:
- OS: Windows Me, Windows 98, Windows 2000, Windows XP or Windows Vista;
- Processor: Intel 1.7 GHz;
- RAM: 512 MB;
- Video Card: 32 MB 3D Graphic Card.
If the requirements are fulfilled, configure your Windows Firewall to allow the connection. For this purpose, go to Start > Control Panel > System and Security > Windows Firewall > Allow a program through Windows Firewall and check the box next to the GunboundWC. If you can't find the game in the Allowed programs and features window, press the Allow another program button, navigate to the installation directory, select the executable file and press Add. After that, from the Advanced Settings select Inbound Rules > New Rule. Check the Port box, click Next, select All local Ports and follow the self-explained steps. Also, make sure your security program doesn't block GunboundWC. If the problem persists, try uninstalling the game and then installing it again.
