I know this is old now, but I just can't seem to do it. When I try to light the first lantern, it says "This lantern cannot be lit." What am I doing wrong? I've uncovered the four markers in other levels, but it just won't let me light the lantern near the gate. I can light the one near the other gate, where you turn off to go to the abandoned truck, just not the first one, Lantern D...HELP!!
