I know this is an old post and the original poster hasn't logged in since February 20th, but this may be helpful to future readers. Concerning the Prismcut not reading the registration marks and stopping short of the third registration mark, I believe it's a lighting issue since this cutter uses a camera to read the registration marks. Make sure the RGB lights are off and turn on the camera light and it should read the registration marks just fine. As for the second question, if I'm understanding the question, the OP wanted to contour cut in the landscape mode instead of the portrait mode. If this is correct, then all one needs to do is to click on the "properties" tab and go into "print setup" and just change to landscape mode. Once you click "OK", you will see the page has turned sideways and you're now in the "landscape" mode.
