Well, I went back to a saved game, found the control panel, saw the wedges, compared them to the wedges on the walkthrough, entered the numbers (yes, first is the bottom one), but no go on the door. Went back to another saved game, tried it again, no go. I have not saved my last game after each of these tries. Not sure what I should do now. Should I get a saved game from someone to get past this point?
