I installed this driver just as I was getting ready to work on my MIDI system. Although at first I am able to see the Fastlane and even test the system, as soon as I fire up an App that uses MIDI, the fastlane ceased to work. It would reset after I restarted my machine. This couldn't have failed at a more inopportune time! What's going on? In Jaguar life was good. If it doesn't work - it is useless.
