I just upgraded to the last version of media player 9 build 2926 and now i can't play .wav any longer.
i keep getting this message :

WMP cannot play the file.
The file is either corrupt or the PLayer does not support the format you are trying to play.



THe files are not corrupted and are simply .wav files ?!?!
Does anyone know what i can try to solve the problem ?
I already checked and .wav are selected as file type....this is weird never had a problem b4 this build......
