Warcraft III error...
 

Everytime I am playing campaign in Warcraft III I recieve a message about a corrupt mp3 or something and it closes the prog. I can no longer advance in the game and I have tried everything from reinstalling to manually copying the file that it claims is corrupt from the iso. I am just out of ideas of what to do.

BTW, the rest of the game (custom game) works fine. I installed it not from a backup CD, but from a ISO mount.

Does anyone know what I can do?
