Every time I try to open a scene in the example projects it dosen't work

Okay I downloaded the 3rd person shooter example project and opened the scene but all i got was a blank scene I have know Idea why the example projects scenes wont work?? Please help

Did you try going to the scene and pressing an object in the Hierarchy and pressed 'F'? That will focus on the object just in case your view isn't focused towards the scene itself.

It's likely that you're not opening the scene at all. Opening a project and opening a scene are two different things. Merely opening a project won't open a scene (unless it includes a scene with the same name as the last scene you had open in the previous project).
