dsPIC33EP512MU810 Error:PK3Err0040

I am using dsPIC33E USB started kit and downloaded the "dsPIC33E Starter Kit CDC USB Device Demo" from "https://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=dm330012".

I did run the demo code with my pic33 micro-controller, but when I wanted to run the program again I receive this error which I don't know how to solve.

It also couldn't program, received an error
"
Programming...
Programming failed
"

even though it couldn't program, I did run it. Then I received an Error: PK3Err0040


I am not that good with PIC micro-controller configuration.

Please help me to solve this problem.

Thank you.

Hi Nantha This usually means the config for the PGED and PGEC (PGEx) are set to the wrong ports there can be 3 try all 3 ,
