try selecting an object in your outliner and hit f.

it might have something to do with your camera's clipping plane - again, select in teh outliner and hit ctrl a for the attribute editor to adjust.

you could also try creating a new camera and see if that helps.

last, have you actually made anything yet? try creating a cube and again hit f just to make sure.

were you able to see objects in your outliner before? if not, then it may be a graphics card issue. try updating your drivers.


hope that helps.
