Does it still work in the background? ie. does it appear in task manager (ccc.exe), can you access it from desktop right click menu or from display properties menu in control panel? I'm not 100% if this bug persists in Windows 8, but in 7 if you have too programs that go into tray during startup, some of them 'disappear', but they are still working in the background.
