Vista & VAC

[doglb]

I am having trouble getting VAC to work with F4AF.
I am running Vista 64 with an onboard sound on the MB. When I am run a test phrase it recognizes the phrase. I am trying to use the Keyboard tester next and not sure how to do this. But when I try VAC in game I get no results. I do have speech recognition running and have set up the mic and trained it.
I have seen that others are having similar problem with games and am wondering if they may have resolved their problem and how?
