Your uninstall might not have been complete. Look into how to get a full uninstall on the ATI web page and then try installing from a fresh download of the latest driver. Also, what OS are you running? It could make a difference. Also, what is the card that you have? These things could help.
On a side note that could help you later, but has nothing to do with your current problem, if and when you do get it working, disable Dynamic Lighting for now. It has a known bug in ground combat on most systems. See
