I though the RME had asio natively? in effect, the card you have is known to be one of the best around, no matter what the price is...

FWIW, the ASIO plugins can be very old school (read: difficult) to install, I feel like I'm back in the days of DOS when I have to copy file X to location Y otherwise, no way it will work!
good luck with getting ASIO happening, I recommend a few searches on AVS forum as the database of information is very large there....
