Skybox Issue...

I was working on my game for PC and my sky box was fine. I tried exporting to android to see what it would do, and it messed up my editor so now my sky box looks like this. If I put a different texture, that texture gets stretched like this too. I can not put any sky box with out it looking bad. Please help. Note: It looks like this in the editor and game view. I am also back in PC mode.
