Winamp doesn't play .wav files

[Beyblade]

Hi, sorry for my English, i will try to describe my problem shortly.

Winamp doesn't play .wav files, i have try to reinstall final version, install older version and nothing had change. In other player .wav files are played good.

i don't know what's the reason. Maybe some on can update for me some "in_wav" files so i can check it on my PC or something else. Pls help
