Unfortunately, there is nothing useful on the log posted, other than your burner and Fab version.
Nothing happened…start and stop time are the same.
My guess here is that your verbs are blank and still usable, at least on this log.
Do you have any logs where the burning process actually started…VSO, Img or nero as long as they were accessed within Fab?
We need some specifics…the devil’s in the details…
