Sure hoping that's not the certified driver version, since that would be from before 2004. Chances are that they meant Catalyst 12.10, which has a 2D driver of 188.8.131.521, since the actual driver version for that is 9.002 . Which version of AutoCAD are you using? And have you checked out the certified driver listing at www.amd.com/isvs ?
