LIVE@EDU Migration to Office365 – Lost Account

Hi, I was migrating from Microsoft Live@EDU to Office365, and as a Result, the user should have two accounts, an Office365 Migrated Account, and a Microsoft Personal Account for using Skydrive, the data that the user was storing should have been kept. We have a User that, trying to logon received the Message "That Microsoft account doesn't exist. Enter a different email address or get a new account". I tried to get support for this issue and was recommended to create a new account with the same name, you'll imagine that I didn't recover the data with these procedures. After creating a new account with the same name, support from Live@EDU can't help me out with this, I still have the URL's of some documents stored in the OLD account that i'd wish to recover. I've been told to ask for help to the skydrive community. Is there anything that could be done to recover those files, and if possible, the complete account?
