Office Mac: New Update Sucks

So I'm working on my wife's iMac and the weekly update for Office Mac pops up and asks if I want to download the update. No problem, I've got a broadband connection so it will take just a minute or two and I need a bit of a break anyway so I close out of Entourage and download the update. When I come back and re-open Entourage it begins to step me through setting up a new account. Translation: The update wiped out all emails, folders, everything is gone. If you think I was honked off you should have seen my wife, so anyway I'll be setting up all of her folders this weekend unless somewhere on my system they are still there and I'm able to import everything. Any help would be appreciated.
