I loaded office 2008 and when I went in to Word for the first time I found ALL my work documents have been CHANGED. Page breaks doubled, spacing off...headers and footers different...It would take me HOURS I don't have to change all these docs. Is there something I am missing? Why did the docs change?

I work with Word & Excel on a daily basis and was having trouble with an older version of Office working with Leopard and was told to upgrade.
