Changes made aren't present when built

Hi guys, I have a problem. Whenever I build my unity project, it doesn't build the changes with it. The changes I have made is to some textures and the placement of some objects. I'm running Unity 3.1.0f3 for Mac if this helps.

Thanks in advance

You need to ensure that the right scene is in the "Scenes In Build" box. Have you done so? It's easy to duplicate a scene, for testing new ideas. work in it, and forget to change what scene will be built.

I have also gotten this error sometimes. Usually deleting the build folder and then rebuilding works for me. I delete my build folder every time anyways as I am working with iOS and some plugins that cause build errors if I don't delete the build folder every time.
