Help with PICSTART PLUS

pic18f2431 fuses

Hi,

I am trying to program pic18F2431 using picstart plus.Below is my code in C which I am compiling using PIC C compiler.After that I am importing the hex file to MPLAB version 8.15a.Then using picstart plus firmware version 04.50.10.Also,I am putting a 0.1uF cap between Vdd and Vss pins and connecting AVdd pin with Vdd pin.

C Code:

#include <18F2431.h>
#include <bootloader.h>
#include <stdlib.h>
#include <stdio.h>
#fuses LP,PROTECT,NOIESO,NOBROWNOUT,NOWDT,BORV45,PUT,CPD,NOSTVREN,NOLVP,NOFCMEN,CPB,WDT1,MCLR,T1STANDARD,WRTC,WRTB,EBTRB,EBTR,DEBUG,WRT,WRTD
#use delay (clock=40000000)
#byte port_b=0x81

void main() {
set_tris_b(0x00);


while(TRUE){
output_high(PIN_B2);
delay_us(500);
output_low(PIN_B2);
delay_us(500);
output_high(PIN_B1);
delay_us(500);
output_low(PIN_B1);
delay_us(500);
output_high(PIN_B0);
delay_us(500);
output_low(PIN_B0);
delay_us(500);
}
}

When I do a erase it says "Erase operation is successful"

When I do a blank check it says

"
Device is NOT blank:
Program Memory
Configuration Bits
IDs
Data Memory
"

When I try to program it says

So,what I am doing wrong.Please let me know.
