I am running Windows Live Mail 2012 and received an email from Outlook requiring me to install the latest update   to continue using Windows Live Mail 2012. 

The update was applied and Windows Live Mail 2012 is working, though rather more lumpy than previously and taking longer to check mail.  On  my pre update configuration I had Read Post,  Sub folders  with a a second level sub folder named with various subjects.  This has helped me manage a complex building project with several false starts.  Anyhow this file system has worked well for me.

The problem is that this second level of sub folders is now lost and all these emails are now all merged, I don't think think I have lost any email's, but if you can't access them quickly they are effectively lost.  Does anybody know of any way of getting my previous read email file structure back.  I have tried playing with various view and filter settings but to no avail ?

Many thanks for any help you can offer.
