pic programeren met wisp628

hallo allemaal,

ik programeer picjes met de wisp628 en werken met de 18f452 ging prima tot ik de pic kapot maakte. ik heb een nieuwe besteld en ook 2 andere (nlk de 12f675 en de 16f676) ik kan deze niet programeren. af en toe werkt het wel en af en toe niet. dit is de foutmelding

weet iemand misschien wat het probleem is? kan het aan de programmer liggen?
