Port authority quest in Eastern Holdings

Hi min the Eastern Holdings around level 54 there's a story quest called port authority that you must complete before going on questing. I tried to complete it but every time I clicked the orbs they all turned on and off at the same time so I didn't know how to complete it. I read somewhere that of your graphics are on low rendering then you cannot complete the quest so I tried turning the low rendering off but it doll didn't work on my computer. Is there a way to avoid completing this quest or some other way to complete it. Thanks
