Make sure you opened After Effects and not the After Effects Render Engine. The icons look the same but you can't do anything but render a comp with the render engine.

If you did open After Effects then try opening it again while holding down Shift + Alt/Option + Ctrl/Cmnd to reset your preferences or just open After Effects/Preferences/General and click Browse to Preferences and rename them and restart AE.
