I am sorry to report that my experience along with that of my students is
that you are out of luck. I have tried the decorruption routine, and only a
small fraction of the stuff is fixed. I have never gotten a satisfactory
answer about why this happens. I run on PC's both W98 and WNT. It has
happened to me with notebooks that have been successfully run then saved
then Mathematica exited - no obvious problems like a crash. Then next time much
wailing, gnashing of teeth, four letter words, and back to the drawing
boards. My solution:
1) maintain a printed copy
2) keep backups.
