I found another site which gave me even more info regarding the Monolith. In the one walkthrough I was using, it says to go to the Exhibit where the calendar stones are, unlock case and take stones. That is not the case because those are nonmoveable. The correct info is that you go to the "God" exhibit and click on the right side where the LG and SM rings are and take them. In the Monolith where there is a side that has 4 holes in it, this is where you place these rings and then the square hole opens up and you put the cube in there, etc. I finally finished and realized that even though I had played this game before, I hadn't finished it because I don't remember seeing Henrik at the bottom of the stairs. So it was nice to be able to finish this game. Thanks to all who helped. Wish I had GB several years ago when I first tried this game.

Great that you finished the game.
