Windows Live Mail Program

I use Windows Live Mail program to get my emails through my internet provider "Telus".  Within my program I had set up many different folders in my In Box to categorize emails that I wanted to keep.  Some how my grand son with the stroke of a few keys seems to have accidentally deleted my email account and suddenly I have no In Box or any subfolders.  I have added my email account again and now all emails from the last last year are downloading, so at least I've recovered my emails but does anyone know if there is a way to recover the subfolders that I had before my account was deleted?  I've looked in the "Trash" folder and there is nothing.   I've also tried system restore to a previous date but I got an error so that is not an option.  I'm still on XP.
