The Maestros should be able to control both analog and digital hobby servos, since they have the same control interface and 3-wire connection.
I do not know how you have your Maestro configured or what settings you are referring to, so it is difficult for me to help you troubleshoot the issue. Can you elaborate on what is wrong with your new setup (e.g. no movement, jittery movement, red LED is on, Maestro resets)? Did anything else in your current setup change from the previous setup other than replacing an analog servo for a digital servo?
Digital servos sometimes need more power than analog servos, so the issue might be that your power supply is not able to source enough current for the new servo. A good rule of thumb is to have a power supply that can provide about 1A per standard size servo.
