You might want to examine how you installed the mod. Chances are that it is not installed properly on your machine. Open up the compressed downloaded file in one window, and your Oblivion\Data directory in another window. Carefully compare the directory trees and make sure that they are both exactly the same. Fix any discrepancies you find.



Follow the installation instructions of the mod. Don't try anything wild with creating OMODs, using fancy installers, mod merging, bashed patches, or anything else of that nature.



A couple of other tests you might run are opening the mod in the CS and seeing if the textures render properly, and opening some of the meshes that don't have their textures in NifSkope to see if they render properly there.



You might inspect to see if the copy of the mod you downloaded is corrupted and damaged. It is faintly possible that you lost the textures during the download, but the rest of the file is still functional.



The last thing on the list would be a freaky archive invalidation problem. This is only if the textures are where they belong and the game is bugging up for no good reason. I don't have any really good advice on how to fix that. But problems of that nature are rather rare, and usually it is something much simpler and more obvious.
