Texture Help

A consistent error has cropped up in my copy and all of my attempts to fix it have failed. This ranges from uninstalling/reinstalling the whole thing to individually attempting to find the problem file.

The symptoms, if the images are not clear, are that anything shiny is covered with the pink/black texture signifying a missing texture.

Any help would be greatly appreciated.
