Hierachy goes blank after import project

hello guys,

I have problem in porting project from one machine to another. All my scenes goes blank after import. Form machine where i am porting, it works fine, but on another machine scenes in hierarchy goes blank.

What i have done: 1. import project as folder. 2. import project as zip 3. import project as package. 4. import scene element as prefab (in this case prefabs goes corrupt).

I am working with unity 5. Any solution to this problem.
