It is impossible to answer all incoming whispers. First check to see that you are connecting to the right server. Right click on your Lineage shortcut icon and click on 'Properties'. Select the 'Shortcut' tab and look at the target Line. Another problem might be that you pressed 'CAPS LOCK' key.
Passwords are case sensitive.
Make sure your Caps lock key on the keyboard is off. You can also use the 'retreive password' in the Registration section of this website to send a new password to your e-mail address. In this case try to connect to the server at a later time. Use port 2000 to connect to Lineage server. Reinstall the game.
