I have a very similar problem here. I made the mistake of trusting Windows easy transfer to save the emails/ contacts/ and some important drafts on the Pc i built for my mum. She had asked me to install XP 64bit originally, but i insisted she let me upgrade it to Win 7, when it was done it had transfered all the pictures and internet favourites, but somehow failed to move over her contacts or messages. It also didn't move over any of her music, just the blank links.
Now i have this old Pc file and i was wondering if there was any way of accessing it to pull the lost files out if they are there?
