I have Windows Live Mail on pc running 8.1.  It's a new pc(5 months old) and W.L. Mail ran fine to start with. NOW, all of a sudden, I am getting a File Not found message when I try to click on files. It started with one sub directory and has moved on to other sub directories. Mail comes into In-Box, I read it and then drag the e-mail to a sub directory. So far so good, the file shows up in that sub directory, the file list  and the preview pane. Then, all the files in one sub directory while showing in the file list now get the error message File Not Found in the preview pane. Spent tons of money to remove hackers and corrupt files from the PC, got a clean bill of health and then more sub directories were affected. Is this a bug with Windows Mail? Can I reinstall Windows Mail?
 Can I recover all those files? HELP!!!!!!!!!!!!!!!!!!!!!!!!!
