K8076programmer does weird

at first sorry for my english it is not my first langguage

So i builded up my K8076 pic programmer an in the first copple of hours i could connect with the pc but i coudnt write to the pic,

but now picprog2009 doesnt recognize my programmer and i get the message " there is no velleman programmer connected to the pc""

what am i doing wrong ?

Please search this forum for possibilities and solutions, mostly an assembly error, cable problem or you tried this programmer with a USB port converter ?
