Yi,
It's difficult to even attempt to debug your setup without at least some context:
I don't know enough about the inner workings of NodeBox to glean much of anything from the error traces. But the first line makes me wonder if you were trying to do something with an external device (e.g. audio processing).
If so, did you check the Device Support checkbox under Preferences in the NodeBox menu? If not try checking it and relaunching to see if that helps.
