Ok I unistalled the 707 i deleted the registry key related to this product. I downloaded it again i have no antivirus and no firewall i installed all as administrator as i have always done and after the plane turn the engines on the wheels disappear and the plane is to throw. So if the antipiracy work with people who buy it as well better to change method or at least to give th e support to solve it. Useless to pay for something and have exact the same result than not payimg it.
