I recently moved "My Music" folder to an external drive-----don't see any way to"Point" Program to new location----moved music back to original location, when I attempt to make a dvd from pictures and Music, the "add music" button doesn't work. How do I reinstall Windows DVD Maker??? It came installed on my HP Win 7 Computer. HP Tech support said I need to contact Microsoft. I don't have a Win 7 install disc to do a "Repair"???
