I recently bought Grim Fandango but the installer doesn't work. Lucas's tech support told me to get the latest drivers for my DVd but I can't find any.

The DVD info:

I rang up the people who sold me the computer and found out that the DVD is an Atapi one, where can I get drivers for it (couldn't find any on this site).

Also in the system control panel under Cd-Rom drive it says DVS DVD-ROM DSR-520H

Please help
