    Gia su patrioti!!!

    Maybe you have locked the PIC and you cant program it any more. I am not an expert in uC programming i know the basics but i heard that if you lock the uC you erase it only with bulk erase. Search for it in google.

    Maybe your usb cable is bad or the connections on the pcb are not good.
