CombineChildren Script help

I assumed that this script would combine meshes to send to the graphics card, it however does not do that, but instead spams me with "Restored Transform child parent pointer from NULL" U'm not a graphics guru sadly and have NO IDEA wghat the hell this means, apart from it's not working, WHY does this script not work, it's supposed to be supplied with unity, these things are not supposed to break, the MeshCombineUtiliy script cannot be added sadly as you get the infamouse "Can't add script" error
