Well Alan, I think we're getting there! You're absolutely right, I did have two instalattions, or to be more precise, I think I sort of have. Some data files are in this so called windows virtualstore and others are in programfiles/airnavsystems/data. From the dates it seems to me that the program is using the ones from the virtualstore. As to the routes I am getting, they are all in the database, when I access to the database explorer, yet I can't seem to get a count......Perhaps it's better to install it again if you teach me how to keep me previous records of spotted aircraft.....thanks
