[Bi-Polar Bear]

I am trying to add new songs from a hard drive. they are mp3g and zip files. If I go to my computer they are on the drive and recognized in my Hoster file. when I go to the add files button and ask the program to add them however it shows the folder as empty and does not recognize anything. this has neverhappened before. I'm using XP. Ideas? Have I brain farted something obvious?
