Please uninstall the client, join our old regular server. It will start the auto download and install. It will close your game and you will need to start it again, then it will resume a few more things and then shut down again. Just start the game again. When you see cOD4x on the bottom right corner of your screen you know you are good and you can join the server. The whole process takes about 5 minutes tops. Yes you do go to the shipment, mod, that's how COD4x installs the client. It's not our server its the COD4x server.
Now if you don't feel like or know how to uninstall COD4x, please confirm that you see cod4x listed on the bottom right side of your screen when you start the game before you press Join Game.
