'I was having problems playing songs on Musicmatch Jukebox, from one of the cds I ripped to My Music. I tried to delete the artist's folder but it won't let me (cannot delete file: cannot read from the source file or disk). I opened this folder and saw two folders with the name of the album on them. I was able to delete one, but when I tried to delete the other I got the same error message as before. Anyone know what's going on here?
