Windows 8.1 preview to release and all emails gone

I was using Windows 8.1 preview, I upgraded to the general release and all my emails are gone. I had half a dozen email accounts and many saved emails, sent and received.   I need those back, nothing was mentioned about losing everything when moving from 8.1 preview to full 8.1. I am very upset, I have spent hours and hours trying to recover and get setting back so I can function again.
