I'm sure they will be.
What host app are you running -- or was that the standalone?
It's a bit preliminary to be pinning blame -- or even to necessarily assume that one non-functioning installation signals they will all fail -- but I noted that it was the 3rd party sector that pushed MS hard to rush the release of Vista (of which I was no big fan, neither here nor there) and then were themselves largely not ready with stable, Vista-ready drivers. (MS shares some blame there, too, of course, since they were changing the feature set [mostly simply removing stuff] perilously close to the release date. But many 3rd parties [but probably not FXpansin, mind you] driven by a desire to churn the market and drive new sales but then not, themselves, ready, deserve special opprobrium, seems to me.)
