Cycles renders using only 4 samples, ignoring the number input in the render options.

Hi there,

Im new to using Blender and Cycles and am having a little trouble getting the renderer to use the right number of samples.

I have a value of 2000 samples set in the render settings, but when I press F12 to render the scene Cycles only goes through 4 sample passes.

Any help would be greatly appreciated.

Edit: Solved by reloading the factory defaults and appending the objects from the broken file.
