When I adjust the brightness level the screen looks exactly the same. The same goes for the color temperature and any other control I adjust. No change at all. Am I doing something wrong?
I have downloaded the application, and it works normally. The latest version available for downloading is 0.5.4, and it was tested on Windows 8.1 Pro x64. I recommend you do the same and download the latest version.

Note: Make sure to run the software as Administrator when launching/installing.
