Hi Has anyone encountered a run-time error '9' whilst attempting to save a project or generate a traffic.bgl file within "AI Traffic V1.0" ?Each time i attempt to either save my project or compile my changes, i get the "Saving AI Aircraft Database" message box but after approx 44%, i get the above error message then AI Traffic bombs out. Failing that, can anyone suggest an alternative utility that will allow me to selectively modify the % traffic associated with a particular airport (as AI Traffic "can" do) ???Thanks in advanceGary
