If you got if from
www.theunderdogs.org, that version comes with the latest patch already installed. (At least the errors I got from it were consistent with that version). Underdogs dont have a manual, but they do have a link to some extremely good fan sites that tell you almost everything in it anyway.
If you get really stuck post here and I or some other TES fan will try and answer - no promises mind. The FAQs cover it all anyway.
