Basically I"m having trouble getting the mod DNGDR (Darknut's Greater Dwemer Ruins) to be recognized under the data files on startup. I have experience using mods before and whatever reason I can't get it to work. I simply just unzipped it and extracted all the files to the Bethesda>>>Morrowind>>>Data Files folder and no dice. Do I need to do something with the Elder Scrolls Construction Set first to I guess "plug it in?" I'm a real newb when it comes to using TESCS

Though this mod is more game changing than the ones I'm using. This mod essentially totally redesigns the Tureynal/Odrosal ruins inside the Ghostgate and the Dagoth Ur facility making the end of the main quest really epic in difficulty, traps, puzzles, length, etc.

I looked at the DNGDR file and there are two folders in it, Data Files and Readme. Just copy the "Data Files" folder into your "Bethesda\Morrowind" folder, not into your "Data Files" folder. You will be asked to overwrite, say yes.
Go to the launcher and check off the esm and esp files. If you're not using NoM ignore the NoM esp.

Yep, I got it running now, thanks. Really freaked out atm because I'm not sure what surprises lay in store for me deep below the evil, dark caverns of Red Mountain...
