I updated my windows 8.1 preview to the final release of windows 8.1 and it didn't seem to keep my windows live mail storage folders.  Is there a way to recover them?  I was still using it because I was getting errors that I using too many folders and could not create any more, is this still a problem?
I have successfully migrated from XP to W7 by first installing W7 on a separate partition on my computer.  I then re-installed my programs andmigrated all of my files to the new partition,  That is, everything except my Windows Live Mail storage folders.  Now I'm stuck.   I have Windows Live Mail working in both operating systems, but cannot incorporate my old storage folders into my W7 version.  I want to now remove the XP partition, but have to keep it just to access my old Email files.
