This is so frustrating! I've got a 12V ac-ac adapter supplied from the same people as the kit. I've been assured it should work. WinPicProg is installed as it's supposed to be. The company that supplied kit and power supply assure me that they've sold hundreds with never a complaint. I'm still getting the same error, and can't see anything wrong! Could someone please supply the hardware setup up required for 18-pin programming using the PIC16PRO and WinPicProg, so i can count that out as the problem?
