I cant export my GIS file, it's only grey when I go to render animation

So I waited a bit before i went to Reddit, but for what ever reason nothing appears when I go to render animation.

I downloaded this program GIS to make a simple location rotation of an area on a map. Not complex only 100 frames.

When I go to view animation, it's just grey.

​

Im curious how to get this to the rendering stage. YouTube videos aren't making this simple.
