Cubase 7.03 + OS 10.8.3 + Apogee Duet 1 = corrupt projects

Hey, just saying in case it helps anyone, twice I’ve started cubase projects on the road using a brand new macbook pro with an old Duet (firewire) - and both of these projects became corrupted so now won’t load. I’m just assuming it’s cause the Duet really isn’t compatible. My card at home is a Metric Halo. I can’t open the projects at home either…
:cry:
