Topic: Pro-Tools 10 / AlphaTrack Stopped being recognized

I have been using my AlphaTrack without issue until last night and during the session, PT said it could no longer talk to the AlphaTrack. I reboot, no go. So uninstalled the driver and the device. Re-installed, rebooted Windows see the unit. Alas Pro-tools cannot speak to the device. Wassup? Any ideas?
