Using WLM 2012 with Windows 8 and trying to back up my mail. Chose Export email, Email messages, Microsoft Windows Live Mail, browsed to and selected a folder I created, selected All Folders, then Next and immediately get a message it's finished.  Nothing actually gets backed up in the folder I selected except a tree of folders that ends with one message.  I've done this back up on this same PC this way numerous times but can't make it work today. Anyone have any suggestions?
