Hmm... I just checked my whole harddisk for other newton.dll's.... found 2 or 3 in directories which are not in any global path-location, but deleted them. Started again (the newton.dll in your blocked directory is the only one on my harddisk), nothing changed... the game starts within a mountain, is this right?
I can move under the terrain, see through the mountains then and see water under my feet. Same in the tutorial. The game start within a mountain....
