So I've had this Willem for about half a year now and suddenly it refuses to blank test or program any chips for some reason, I'm not sure why it's doing this but it only programs fine using the same data from the chips it reads. Several months ago, it programmed roms fine but now it doesn't want to do anything but just read and program the same data that's on these M27C801 EPROMs. Can anyone help me out here?
