Unity Error - ? SceneCamera

I opened up Unity today and this error keeps coming up. I have no clue as to why or how it happened. The annoying thing is that it is consistent through out all of my projects now. Could some one please tell me how to fix this or why its doing this, or even what it means. Any help would be nice. Thank you.

transform.position assign attempt for 'SceneCamera' is not valid. Input position is { NaN, NaN, NaN }.
UnityEditor.DockArea:OnGUI()

Did you move any files while your previous Unity session was open?

Nope. All I did was add an follow script to a camera, the one that comes with unity. I notice ed it after that. The error persisted even after I removed the script from the object.

Edit: It was in a new project too.

Try Window > Revert Factory Settings from the menu

Thank you, that did the trick.
