Items missing from File Menu

I just downloaded DVR 15 and opened a project as a test.
But when I wanted to close it I noticed there is no File - close project menu item, the file- switch project item also isn't there?
Why are these menu items not there? I can now only close a project by closing the application.
How can I correct this?
