It sounds like you do not have Archive Invalidation Invalidated active. If your using FOMM click "Toggle Invaladation" and click yes to apply. Or download it http://fallout3nexus.com/downloads/file.php?id=944. This is required to allow the game to use textures that arent part of the default game.

Install http://www.fallout3nexus.com/downloads/file.php?id=640 and click its "Toggle invalidation" button.

Have you got/activated ArchiveInvalidation Invalidated?
