hi guys,i am new to programming but i'm trying to buidl myself quickly.i recently made my own jdm programmer using a schematic i saw on the net. I then used mplab successfuly to build and complile in order to produce the hex file i need to burn on my pic.I then downloaded winpic800 to burn my pic,everything works fine hardware test is ok,i can read data and code and even the settings successfully and i programmed my PIC16F877A successfully but when i try and verify i get the following error:

Error-> Verifying address 0x002003
Verified: 0x0001 Read: 0x0000

Please help i dont understand what im doing wrong,my first program was a simple c code to blink an led in ports A of the pic
