A3XX Fuel Planner has stopped working

[Drew Melia 2]

For some reason, my Fuel Planner stopped working this morning. It is not calculating distances between airports. I removed all the files from ..

C:\Users\melia\Documents\Aerosoft\General\A3XX Fuel Planner\loadsheets, and the settings file, no joy. I'm on the latest build. If I enter the distance manually, it works. 

 

So where does it calculate the distance from? It must look it up somewhere?

 *** EDIT its OK its working. I had to allow it through the firewall. Never had to before, I wonder what changed? Gotta love Microsoft for all these stealth updates!
