Morroblivion

Hey, well i just downloaded morroblivion and did exactly as the readme told me to. so everything's fine i go to anvil, speak with the guard, and we both come to morrowind, at start i was really excited, we were in the ship, was really nostalgic. So when i exited the boat i found myself to be underwater, after i swam up i noticed there is no land and buildings, only doors and swimming people, well trees and rocks also. Can anybody tell me what's wrong?
