Ah cool.
I'm not completly dissing the interface. I had an M-Audio Firewire 1814 for years before, and that was endless terrible, despite two of my laptops having the appropriate Firewire chip. I've had my Quad for over 5 years now and it sometimes disconnects, but since Sonar has improved the ability to re-connect with Audio and midi devices, it's much less of an issue.
Glad you are all sorted.
