I have been adding lots of airport gates data to my \Virtuali\GSX\ folder using the functions provided within GSX. But now the option to add any further airport gates has disappeared. I was adding the first gate of my 35th airport.
Is there any connection with it being the 35th airport i.e. is there a program limit set? If not, how do I restore the option to GSX? Restarting FSX does not restore the option.
