You should be able to remove the outer trim ring by pressing down on it gently yet firmly, at the same time give it a twist to the left (counterclockwise). If this does not work try twisitng it clockwise instead. Most come off by twisting counterclockwise but I have heard of some which require a clockwise twist to remove. Once this is removed the glass can be removed. Be careful as the glass will fall out once that trim ring is loosened. Replacement is the reverse of removal.
