Importing Accounts data – “no entourage 2004 identities found”

I'm upgrading from Entourage 2004 to Outlook 2011. I'd originally tried doing a direct import, but when Outlook went searching for my Entourage identity, it gave me the message "no entourage 2004 identities found". So I generated a .rge file to transfer data to Outlook. However, Outlook didn't import my accounts data.

It's been years since I set all of this up, and there are nuances that I can't remember at this point, so creating the accounts from scratch in Outlook isn't a good option. How can I make this work?

Thanks.
