Can't make my k8076 work

Hi,
I just assembled a K8076 PIC programmer, but can’t make it work. the hardware diags appear to work correctly, and I have doublechecked my work.
I have tried 16F628 and 16F84A PICs with the same results. Program button causes popup saying “settings don’t match pic in the programmer”, Continue tries to program, but ends with “Error Writing to PIC”.

Suggestions?

Thanks!

does your pic use a external clock or x-tal?

Are you sure that you are using a real (native) RS232 port and not an USB routed one ?

Check that the input voltage is at least 15V
