There is no common cause for this error. In most cases, the issue is related to network adapters and applications that are installed and control the network adapters. Try turning off Windows Firewall if it's active or disable the Internet Security application for the time being. Also, you may try to uninstall the application and then download a new package from the official website and install it. If you check various support forums on the Internet, you'll see that re-installation would often fix the problem.
