Ok further to the issue with the melbourne, sydney, brisbane, adelaide maps. I downloaded Paris and New York and they worked fine in EPM Mode. On the other hand ALL the Ausralia maps come up with "Unable to Unlock maps" this actually happened the first time I downloaded but I just automatically went ahead and unlocked with FIA 2.1. So it would seem to me as a novice tha in fact these maps HAVE NOT been modified to work with FID 800. I await the input of the experts.
