I really F***ked up my computer. I was messing about with themes and got a really cool looking one for my pc. But now for some reason when i Click "save as" or when i go File>open in programs like Itunes, the section of the explorer window that lets me choose the folder (where you can see music, pictures, documents and drives etc.) is completely blank. I reset as much as i could back to normal but its still the same. Can someone please tell me how to get the computer looking the way it did? I have windows 7 64bit. All help is appreciated.
