Closure of Windows Live mail account

I recently inadvertently closed my live mail account. I thought I would be able to reload it. I didn't realise that it was finished and I am not able to reload it. My Contacts list and most of my Folders and sub folders have disappeared. Is there anyway that I can retrieve this information. It must be on my computer somewhere. I have opened an outlook.com account but am not able to get a contacts list or much else.
