The same thing has just happened to me so I'd also be interested in any replies. I am running Windows XP home, and trying to use the voices with the free Thunder screenreader. Only the one Sapi 5 voice works, but I have used Sapi 4 ones before (although not with Thunder).

I put out a message on this issue yesterday but had no comeback on it. BAsically, I cannot get my sapi4 voices to work. They are all showing up in my list of syntasisers but when I select one, my computer goes silent.
