Change the server IP of a old server if you play a new server, and the new server if you play an old one to your default loopback IP, then change your proxys connection to the other. Make it so, when you start conquer you don't get an error, but when you try to log into Baby Icy server for example, it would log you into Dragons via your proxy instead. I don't use a proxy or I'd step by step you. No +k is needed I won't use it for anything anyhow.
