CRIO Slot 4 "Digital module 4 is not present."

We have reimaged the CRIO with the slots in 1,3 and 4 (1=analog,3=pneumatic,4=digital) and deployed code where the speed controllers are declared using
Code:
SpeedController s = new Talon(4,1);
The digital sidecar is powered and works when in slot 2. The digital sidecar is powered and works when in slot 2.

Output when deployed:

Code:
[cRIO] Digital module 4 is not present.

We made a new project with only creating objects and it still gave this error. I am 100% sure it does not instantialize the object more than once. Any ideas?

Full code of test:
Code:
public class Test extends IterativeRobot {

    private Joystick j = new Joystick(1);
    private SpeedController s1 = new Talon(4, 1),
            s2 = new Talon(4, 2),
            s3 = new Jaguar(4, 3),
            s4 = new Jaguar(4, 4),
            s5 = new Jaguar(4, 5),
            s6 = new Jaguar(4, 6);

    /**
     * This function is called periodically during operator control
     */
    public void teleopPeriodic() {
        double speed = j.getRawAxis(3);
        SmartDashboard.putNumber("Speed", speed);
        s1.set(speed);
        s2.set(speed);
        s3.set(speed);
        s4.set(speed);
        s5.set(speed);
        s6.set(speed);
    }
}
