I would UNINSTALL both the drivers and the control panel and reboot. When windows asks for the driver for your video card run the ATI driver installer and pay attention to the directory it extracts all the files to. Once it's done extracting the drivers and asks if you want to continue cancel it. Now you should still have the new hardware wizard open so point that to where the ATI installer extracted the drivers. Install both drivers this way. Then install the control panel and reboot. That's how I enable texture acceleration, I've never heard of that guys way.
