Gameobject not visible except for hierarchy

Hi i just made a shooter game where player shoots objects for points. The game works perfectly fine in game view of the Unity engine. But when I make an exe file the objects go invisible. None of the objects are visible but they are present there as I still collide with them. I am working on Windows7 32 bit system. Fact being that the trail renderers and skybox are visible and everything works perfectly fine including scoring, collision, lighting and even the gameover screen and timer. just the objects go invisible. Please help.

Could be your render settings, or the import settings of your textures.
