Forum:Boot up the Mainfame?

Xbox 360 version: Alright, I've got a major issue, maybe a glitch. I'm at the Waters of Life quest, and Dad tells me to boot up the mainframe. I opened the door, went inside, and presumeably hit the switch. I can't entirely remember because I was busy and saved and quit imeediately after I pressed the button. Now when I loaded the game, the switch is green, but my Dad keeps telling me to boot up the mainfame, but the lights are on and it's kinda obvious that I did. I've hit the switch, walked around and attempted to progress the story, but can't get past "Boot up the mainframe". Any ideas or sugguestions?
