How much voltage you will have on MCLR/VPP pin when you enable Vpp (+13V) from Interface Test (Interface sheet)?
With JDM and standalone PIC I have 10.4V and with ICSP (PIC on applicatio board) 9.3V and it is still working. Sometimes ICSP needs more flashing trials to avoid errors. I think it is because of lower VPP voltage..., but not sure.
When it says "Initialising PIC-Programmer: Success." is should have all setting correct.
