From what it seems, there is a connection problem caused either by your network connection or by Metin2 servers. If the Metin2 servers are temporarily down, you will need to wait for a while. If the problem is caused by your network connection, go to Control Panel > Network and Internet > Network and Sharing Center > Local Area Connection and press Disable. After that, reboot your computer and go again to Control Panel > Network and Internet > Network Connections, right-click the Local Area Connection and select Enable. In addition, open your browser, press Ctrl + Shift + Delete key combination and clear all cache, cookies and temporary Internet files. If the problem persists, uninstall the game and download and install the updated version of the client. When you launch the game, make sure that all unnecessary programs that may use your Internet bandwidth are closed.
