My active ILS is not working.

You must DESELECT the ILS you do not wish to use. To do this you must be in the MAP mode, push the ALT key and the letter J at the same time. Place the + over the orange dot on the ILS  antenna to deselect and LEFT click. To cancel or return to normal operation, press the ALT key and the letter J again at the same time,  place the + over the shaded dot on the ILS antenna and LEFT click.
