Oo everytime i burn the program i would received the verify error and i thought my burning process failed already, so i never test my pic. When i read the pic using IC-Prog the Address Program code would all turn to 3FFF. ok i'll try to adding the resistor and test it again. Thanks for the help
This indicates that your programmer hardware has problem or not properly setup or there is communication trouble between PC and programmer.
Inside IC-Prog, there is a pull-down menu for hardware check under "settings", with several tick boxes inside the "Signal out" section.
With no PIC in the socket, place a voltmeter between 0V and the following pin , tick one box repeatedly, with a tick a voltage should be presented and gone when there is no tick:
1) socket pin 14 and tick the box "Enable Vcc", you should be able to control the +5V ON/OFF
2) socket pin 4, tick box "Enable MCLR", +13V On with tick, OFF without tick
3) socket pin 12, tick box "Enable Clock", +5V with tick, OFF without
4) socket pin 13, tick box "Enable Data Out", +5V and
a tick will automatically appears in the "Singal In" box. Tick the box again and the condition returns to normal
If any of the above tests failed, try to find out the reason why. If it appears to be reversed, (ie. voltage without tick and voltage gone with a tick) then you have to select "invert" on that signal under the "hardware" pulldown menu.

sorry forgot one more question, the c1 10uF capacitor, i'm using electrolytic cap 16v, would this be the problem?
Its fine on 12V or 5V circuits.
