It's very unlikely that an update has changed the formatting of a document.
Exactly what do you mean by merge to bookfold? When you open the main
document before executing the merge, what does it look like?

Today when I merged to bookfold it will merge alright but as soon as I
click
print preview it messes up. The margins are way off and it prints very
small
in the center of the page. I have merged to Bookfold many times and
it's
just today that this is happening. I have run my virus protect it's ok.
ask
a friend to merge it and they are having the same problem

Could one of the updates have messed Word up?
