Cant see previews of grasshopper in Rhino 6

It seems i cant see anything in the rhino window when i preview geometry from grasshopper functions.

Are you in Render view?There are several threads about this topic.

No my viewport is in shaded or wireframe. my classmate just bought too and if we dont bake the geometry it wont preview it.

In the right corner of the gh canvas there are some options. Preview selected, preview all etc. You may have the wrong settings?
