Fliteman,
The keyboard rudder keys are mapped under the keyboard mapping option. It is not a joystick function. Go into setup/keyboard mapping and in the flight section you should see the a,s,d keys mapped for left, center,right. If they are not you can change it.
Sometimes someone will go in and remap a key not realizing that when they do they may be changing an existing mapped function.
As long as your keyboard works and you don't have a joystick rudder input then this should take care of your problem. If you have either a set of rudder pedals or a twist grip joystick setup then they won't work because the joystick will take precedence.
Hope this helps.
