Windows Live Mail

I have been using Windows Live Mail on my laptop with Windows 7 for several years.  All of a sudden, it no longer shows me the list of all my emails in my inbox folder.  I have tried going to View and Quick View to see if I can change the layout, but it does not seem to give me any option to switch back to what I had before.  It now only shows me one message at a time, and the only way I can see another message is to delete the one on the screen.  Please help!
