Unity blue screen Problem, Cant navigate screen.

So I’ve been using unity for a couple of days now and it was going smoothly until I started a new project it just starts with that plane blue color in the background, I can’t see the main camera and that grey rectangle is the terrain I tried adding. Also I cant navigate/pan around the scene at all and I cant add any assets. Here’s a picture Sorry I cant explain things well. alt text

Any help would be much appreciated! Thanks in advanced

This is because you are the the Game windows.
Near the top (middle) there are two tabs: Game and Scene.
The Scene tab is the window you use to edit the scene.
