I just received my enhanced JDM programmer and I'm trying to program a 16F84A and I receive the error message:

ERROR -> Writting address 0x000003
Written : 0x0070 Read : 0x0000

I'm using winpic800 ver. 3.59
RS-232 straight through cable
Jumper set for 18 pin
I've tried both internal and external (12 volts) Vp
I've verified proper placement of PIC
I selected JDM programmer within winpic 800
com 1 (I do see the red LED flash when it tries to program)

Green power LED is on and the red PRG LED flashes briefly before fault occurs. I've also tried to program a 16F677 and had a similar failure. Anyone have any suggestions on what I should try next? or do I have a bad programmer?
