The Ai package that I have contains a traffic Bgl as well as the flight plan files (3) The instruction is to recompile the Traffic file using the flight plan files. My problem is that The program will not allow me to delete the existing Traffic file. Any help please??

If you're talking about TrafficTools you don't have to delete anything. Simply change the FP and recompile. I hope this helps.

After changing or adding a flight plan, when I try to recompile using ttools it tells me it "can't delete the old traffic file". the new flight plan is of course then not included. Used to work OK but I have windows 7 now. would that have any effect? thanks

Before starting TTools, right click it and choose Run As Administrator.
