Problème lors du lancement de Quake 3 [RÉSOLU]

Bonsoir!

J'ai très récemment obtenu Quake 3 mais un message s'affiche directement, le voici:

Ensuite plus rien.

J'utilise Windows 7, et comme lu sur un autre forum j'ai téléchargé DirectX 9 mais rien y fait...

Est-ce que quelqu'un sait m'aider?

D'avance merci.
