Every time that we run the code we enable the robot and then it disables and displays the error :
ERROR Unhandled exception: edu.wpi.first.wpilibj.util.AllocationException: PWM channel 4 is already allocated at [edu.wpi.first.wpilibj.PWM.initPWM(PWM.java:126), edu.wpi.first.wpilibj.PWM.<init>(PWM.java:145), edu.wpi.first.wpilibj.SafePWM.<init>(SafePWM.java: 33), edu.wpi.first.wpilibj.Jaguar.<init>(Jaguar.java:48 ), org.usfirst.frc.team4284.robot.Robot.teleopPeriodi c(Robot.java:68), edu.wpi.first.wpilibj.IterativeRobot.startCompetit ion(IterativeRobot.java:150), edu.wpi.first.wpilibj.RobotBase.main(RobotBase.jav a:234)]

We had a jaguar plugged into port 4 and then we un plugged it and it sill displays that error.
