Nokia N72
Music player not able to open music files

Hi, I have Nokia n72 mobile. Yesterday, when I tried to open music files from music player. First, it shows "opening" message, then it shows " processing", but after that it suddenly comes out to the main screen. I tried to open my music files many times and the same thing happened again and again...

Is this related to any virus or memory card corrupted?

Please, help me, regarding this.
