AxWindowsMediaPlayer播放视屏闪退

[那城]

string onepath="1.wav";

axWindowsMediaPlayer1.currentPlaylist = axWindowsMediaPlayer1.newPlaylist("aa", "");
                axWindowsMediaPlayer1.currentPlaylist.appendItem(axWindowsMediaPlayer1.newMedia(onepath));
                
                axWindowsMediaPlayer1.currentMedia = axWindowsMediaPlayer1.currentPlaylist.Item[0];

this.axWindowsMediaPlayer1.Ctlcontrols.play();

播放几次视屏后AxWindowsMediaPlayer播放器处于连接中，然后出现闪退，报出错1000
