Hey there, I also got a blue screen when trying to reset the Asio settings in the control panel, but even though I didn't change them, everything works fine and the quality is good.
The only problem I am dealing with now is that sometimes the card de-activates unexpectedly or it goes crazy and starts producing sounds out of nowhere, like echoing some of the internal computer sounds.
I suppose that I will eventually have to switch back to XP, or buy a new card. Pity, because this card was exactly what I needed and served me great for so long.
