Are you using updated ATI drivers? If not, go to ATI.com and download and install the version for your operating system. If you are using generic drivers (Windows default drivers), you may not be able to launch the game properly. Regradless, having the current drivers will help your overall performance. Good luck!!!
i'm sure since it's a laptop the OEM, installed at least some version of the ATI driver possibly modified, but at least some for, you should updated to the latest that's available
