I have the current versions of Snow Leopard. I was changing some of my icons and now one of them (the Documents icon) for the documents directory is showing a default white page with little photo icon. No matter what I do it will not change back the the blue documents folder icon or any other icon. I have use CandyBar and LiteIcon, and I have manually tried to change it by dragging the icon in the "Get Info" screen. Nothing works. How can I fix this?
