Nothing in scene/game view

I've recently imported an existing project containing a full running game into Unity. However, nothing appeared but if I were to drag something into the scene view, it appears and stays there. I tried to build and run the project, it works fine. Every assets are in there and the game works perfectly. Had my layers set to default and tried double clicking my asset where it is suppose to show me the location in the scene view. I'm running the same Unity version on my laptop and where the project was built.

Please help. I need to rush this project for my assignment ;\
