El,
HERE is another WT where you will see with two pictures what I mean by the lower bubble in the cauldron being the center of the puzzle.
You do not move the center of the puzzle but the circles around it.
Scroll down the page to see the pictures. They will help you to comprehend the puzzle.
And since I played the download version, I do not have a save for you and could not send one anyaway.
Now, where is the game in your computer?
If you are running Win XP, it can be in My Documents or Program Files (or maybe in Documents and Setting????).
If you have Vista or Win 7, I have no idea where the game is.
Chief
