So I wanted to try out Microsoft Anna one day, and as I waited patiently for her to say something I finally realized that she just wasn't going to.

I can not hear what she reads. So I thought maybe my sound was off. I tried a song, and it worked fine. I went back to Anna, and she still remained silent. What am I missing?? I've turned all the volume controls up. Is there any way I can reinstall Microsoft Anna?? I've searched but I can't find a download for her.
Any and all suggestions would be appreciated.
