1: run checkdisk utility to repair any dumped areas. sometimes you to electricity failure or some other reason some files get dumped.
you can run checkdisk utility by pressing WINDOWS LOGO KEY + R and then enter "chkdsk" in the pop-up window and press ENTER. after that select the drive on which you have installed that software.
