Uninstalled Windows 10, lost all emails WindowsLiveMail

Hi. I upgraded to Windows 10 but decided I didn't like it. After seeing we could roll back to Windows 7 (or 8) I clicked to roll back and uninstalled Windows 10. All was fine with Windows 7 starting again until I opened Windows Live Mail. All of my emails are gone. I've tried importing them from where I thought they were located (ie. Appdata/local/Microsoft/WindowsLiveMail. It seemed to be importing emails however when I looked I discovered they were my old, old emails pre-2012, from when I had imported those ones from an old computer onto my current one. I tried again and found a different location (under different User... one had been my name, one was admin)... and imported, these looked like the right folders, but when I click to look in them (in storage folders and then double clicking each folder) nothing is there. It looks like new folders have been made. My hotmail emails seem fine but I don't often use that account. It is my other personal email addresses and website email addresses that I am more concerned about. Anyone else rolled back from Windows 10 to Windows 7 or know where the emails could be.  How can I get them back?
