All I can find is a RED EXCEPTION in the log around the time that this happened...

I don't know if this has anything useful in it.  But the copy did generate a run-time error.

You can contact me on msn messenger  if you'd like me to take a look.

Ok, from your last statements, it sounds as though it is just one articles module that is not showing it's content.

Before you go any further you should get a backup of your database.

Then we need to see if the articles module is missing it's content, or just somehow not connected to it anymore.
