You may want to posibly try this, I changed some things that might make it work a little better(or fail miserably):

#pragma config(Sensor, in1, pot, sensorPotentiometer)
#pragma config(Sensor, in3, LineLeft, sensorLineFollower)
#pragma config(Sensor, in4, LineRight, sensorLineFollower)
#pragma config(Sensor, in5, LineCenter, sensorLineFollower)
#pragma config(Sensor, dgtl1, touch, sensorTouch)
#pragma config(Sensor, dgtl2, Encoder, sensorQuadEncoder)
#pragma config(Sensor, dgtl7, Encoder2, sensorQuadEncoder)
#pragma config(Motor, port2, arm, tmotorServoContinuousRotation, openLoop)
#pragma config(Motor, port3, elbow, tmotorServoContinuousRotation, openLoop)
#pragma config(Motor, port7, rightMotor, tmotorServoContinuousRotation, openLoop, reversed)
#pragma config(Motor, port8, leftMotor, tmotorServoContinuousRotation, openLoop)

int threshold = 2000;
void lineFollower(int speed);

	while(true)
	{
