I'm using Windows 7. GF told me she copied some MP3 files to an external HD. I think she may have moved part of the directory. I tried renaming things but although the name in the directory is correct the screen display is wrong. Not a big thing, i'm building a new PC and there were only about a dozen progs accesible from the desktop. When the new one is up and running i'll formatt the disc and re-install the software
