Wab Lost, please help

Please Help, I recently upgraded from Windows ME to XP Home ed., I lost my address book data in Outlook Express, do you know anyway I could attempt to recover it? (yes, I know I should have backed it up, but it?s too late now) I had some important addresses in it. Could you give me the path to WAB that Windows ME uses?

Thank you for your time, Henry Matusevic
