What Rob said - you've got to give Maxim/Pinpoint something to start with, ie. a rough location from which to start searching for catalog stars to match up to your image.
By talking to the mount (click on the observatory button), you will drag a rough RA and Dec into the FITS header, which is then used by pinpoint to start the solve. Telling Maxim you scope and camera details lets it work out an image scale.
Unfortunately, it's not a mind reader...
