.mp3 wont play...?

I have a few .mp3 that wont play…???
I have codecs installed (AC3 / Fraunhoffer mp3)
even VLC player wont play them
I have WMP 11 with DivX / XviD / AC3 / MP3 codecs installed…
does anyone know why WMP/ VLC or Real Player wont play these files?
(also NERO wont burn them…when it goes to check the files it freezes until I intervene)

Any help would greatly apreciated


Sounds like (no pun intended) they are corrupt. Not sure what you can do about that.
