First of all, this kind of problem is always repairable, as long
as the audio files are still there (which they will be).  Strange
that you'd hit this with no apparent change in software, but to
fix it you will need to edit the rawee.ardour file in a text editor.
search for the id # mentioned in the error message looking for
the <Region > that references it.  Then remove that region from
the file by cutting out <Region>...... </Region>.   

If you see the Source in there with that ID, all the stranger,
but note the filename, because you will need to import/embed that file
from the sounds/ directory as a new region back in ardour.  You
should be able to deduce what file was missing by its filename.

Make a backup of your broken session file (and send it to me too).
