Music not playing suddenly and showing greyed out quicktime box? huh?

Ive added music files (mp3) to wandabarrett.com (mp3) a long time ago.
They played fine excellently until....
All of a sudden they dont play anymore?!?

Ive tried re-uplaoding the files;
going into control panel removing mp3s
then reuploading it again.
and nothing seems to work?

How come it just stopped working? and why if I insert windows media player box while in editing mode; does it show a greyed out QuickTime player live on the website??

PLEASE HEALP!


Cordially,

Oni
