I'm probably being a bit think but I can't work out what to do.

I approach the Outpost which is firing its guns in the direction of the L4 Lagrange point, then it blows up and I'm told to track the ships through one of the Points. But when I go to
either L4 or L5 nothing happens. The Capsule drive doesn't engage when I pass through them and there's no indication that the Device has found any trace of King's ship.

what is it i'm missing?

Thanks in advance

You have to manually click on the device, then it will set the destination and you can jump.

Thanks, just finished it. FYI the device is in the top Right had corner of the Command (F1) screen
