I've just downloaded the free version of A1 Website Download and can't get it to scan. I've tried different combinations of settings but all the same result. As soon as I press 'Start Scan' it shows a Scan State of 'Preparing' and just sits there. It will stay that way for hours. If I press 'Stop Scan' it just hangs. I have run a basic scan by just entering a path and nothing else but same result. And I have tried 3 different websites. What have I done wrong?
