I am running Windows Live Mail on Windows 8.1.  When I got the new computer I imported all my old E-mails from my XP Outlook into a Storage folder.  No problem there, I was able to access all these files.  Now some of these folders are showing that there are messages there, but when I select one I either get an error "Message Not Available" or another message from the folder will open in place of whatever I selected.  Other folders seem to be unaffected and I can access all messages, for now at least.  The problem is not just with the messages that I imported from the old Outlook, but affects more recent messages from the new LiveMail, but stored in the Storage folder.  Any ideas?
