Where did you purchase the Vocalizer Voices? I bought mine from Code
Factory, and I too have had some issues with the voices not working.
I think mine was caused by my getting an update to Win 7. this might
have been about 8 months ago.
I have contacted Code Factory, but nothing they told me to do has worked.
I was finally told I may need to reinstall Win 7, and then everything
When I asked what files could I erase, that were Code Factory files,
they acted dumb and never responded back.
So, on that machine, I am using Jaws only.
