Could anybody advise on using a scanner adapter for a a perfection 1200 photo scanner. I think it might be a software problem but been to the site and nothing mentions software using this adapter that came with this scanner. When we set it up and put a slide in, we try to scan and the green light on the adapter goes out and it does nothing else. The light is on before we try to scan it though. What are we doing wrong. We have no instructions for the adapter neither.
