FCP to Motion link suddenly ceased working?

FCP 6.06, Motion 3

For four days I've been working seamlessly with FCP - sending sequences to Motion to animate. Everything exactly as it should be. Suddenly Motion is telling me "The document xxx could not be opened." And when Motion opens there are no clips there.

I've trashed preferences on Motion, FCP, twice. I've fixed permissions. I've rebooted. Same problem. Motion works perfectly on its own. Final Cut works perfectly on its own. I've created dozens of sequences since last Friday, successfully moving back and forth between the two apps. And then suddenly I'm getting this message and Motion won't accept anything from FCP. I've tried different projects, different clips (mostly stills). The material is exactly the same that I've been working with all week.

Any ideas out there? Anyone heard of this particular little bug?

I would try logging in as a different user, see if that works.
