My picture has dissappeared from my purchase of start8.

My start8 is not working at all on my desktop PC. Really annoyed when I have paid for the license. I have no Windows 8 Metro Button leading to my apps any more. So I have no direct way to get to my apps on my start menu which is crazy. I have no picture of me from my Microsoft account showing. I have nothing in my administrative tools folder or maintenance folder. I duno if this is suppose to do this running windows 8.1 or not with nothing in those folders ? Any idea of how to fix this ?
