Issues with windows in 8.0

I just updated to 8.0 and I'm thinking something went wrong during the update. I'm unable to close, minimize or resize my windows. It looks like the frame around the window is missing. I can only close the window through the menu, if the option is there. This is on anything I open. (screenshots attached)

If I go to System > Preferences > Look and Feel > Windows, I receive an error message that says "The current window manager is unsupported.(screenshot attached)

Is this something that can be fixed, or do I need to do a fresh install of 8.0?
