No audio devices in 6.07

Just updated to 6.07 (from 6.05 which was so buggy I rarely use it these days…) and now I see no audio devices whatsoever. I have a Yamaha N12 and 2 Steinberg MR816. Pro Tools 9, Logic 9, Studio One V2 all see with no problems. What’s the deal with this update?
Any ideas please. Macbook Pro, OSX Lion
