Requesting help with a tedious bug

Hey, I just downloaded Morroblivion from this website, and I am experiencing some major problems with it. Objects, structures, patches of land, all have disappeared! Entire buildings vanished, leaving nothing but floating doors; sheets of earth gone, leaving voids filled with water; objects missing, leaving leaving broken bridges, doors without anything to attach them to the building, (I.E: Vivic) and much more in it's wake. I have neither Morrowind nor it's expansions, but I do have both Oblivion and Shivering Isles. Please, show me some kindness and address this problem? I'm probably not the only person in the world who has this problem, so you'll prevent this from popping up later if you answer this now.
