I tried to do what both of you( w6kd and franjoflyer ) suggested but i still get the same problem.
Besides it only happens in England. Other countries and cities are fine.
I use aerosoft Heathrow Professional v1.01 and all ORBX Products lc base vector libraries but i dont use EU England.
Here is a screenshot of the problem.
