You are having problems - but you need to share more details about what you are doing when it doesn't work. Just like when taking a car to the mechanic, share what is going on so that people can pinpoint. As you can see in my video below - I had no problem. Are you visiting it at night or a different time of the day? What point of the game are you in (just started, you have completed xxxx in the main quest, or completed all quests, etc)?
