Thanks both of you for your response! I will postpone the idea of downgrading the database for a while.
Zeno, I'll take a look at code to find out the exact problem, but looking at the snippet code in the email, this could be because of malformed ISBN, I guess. I will write to the list, if I come up with solutions.
