I too have had this problem with books that I have created and are on the hard-disk. It happened once and it has not happened since. It was a pain to make the entire book again, it included about 50k games from the TWIC site. It doesn't happen when you use the book on the cd-rom of course and it doesn't seem to be that big of a deal unless it happens more than on rare occasions.
