I downloaded JackPilot, go to my apps folder, double click on the app, the picture appears on the bar for half a second and disappears. That's all it will do, I can't get it to start half a second before it crashes.
I suggest you open Applications -> Utilities -> Console. Clear its contents. Start up JackPilot. Report back with what appears in the console window.
