I could not get the mod to work either. Went to Dead Man's Drink each time and there was no door. Also the skyrim launcher never gave me the option to add data files. Finally got it working by doing this:
Go to C:\Users\<User>\Documents\My Games\Skyrim and edit the SkyrimPrefs.ini file
Scroll down untill you find [LAUNCHER] and paste the below 4 lines in underneath.
