PIC18F4520 PK3Err0040: Target Device Not Ready for Debugging with PicKit3 & MPLAB

I am trying to run a program on PIC18F4520 using PicKit3 & MPLAB IDE. But I am getting an error: PK3Err0040: The target device is not ready for debugging. Please check your configuration bit settings and program the device before proceeding.

Whereas when I try to run one of the old program, its running. My new program code which is not running is:

Code:

#pragma config OSC = HS,FCMEN = OFF,IESO = OFF              // CONFIG1H
#pragma config PWRT = OFF, BOREN = SBORDIS, BORV = 0                       // CONFIG2L
#pragma config WDT= OFF, WDTPS = 32768                                    // CONFIG2H
#pragma config MCLRE = OFF, LPT1OSC = OFF, PBADEN = ON, CCP2MX = PORTC       //CONFIG3H
#pragma config STVREN = ON, LVP = OFF, XINST = OFF                // CONFIG4L
#pragma config CP0 = OFF, CP1 = OFF, CP2 = OFF, CP3 = OFF                   // CONFIG5L
#pragma config CPB = OFF, CPD = OFF                                         // CONFIG5H
#pragma config WRT0 = OFF, WRT1 = OFF, WRT2 = OFF, WRT3 = OFF                // CONFIG6L
#pragma config WRTB = OFF, WRTC = OFF, WRTD = OFF                            // CONFIG6H
#pragma config EBTR0 = OFF, EBTR1 = OFF, EBTR2 = OFF, EBTR3 = OFF           // CONFIG7L
#pragma config EBTRB = ON                                                  // CONFIG7H

#include "p18f4520.h"
#include "delays.h"

void main(void)
{
TRISA=0b11111111;
TRISB=0b11111111;
TRISC=0b11111111;
TRISD=0b00000000;
TRISE=0x11111111;

while(1)
    {
     Delay10KTCYx(200);
     LATDbits.LATD3=1 ;
     LATDbits.LATD2=1 ;
     LATDbits.LATD1=1 ;
    }

}

Please let me know where the issue is? is it something to do with bootloader?

 

Could you show your previous code? There is that slight possibility your configuration gone wrong, maybe the overwrite pin is not enabled or something..
