Problème counter strike source

Salut tout le monde, avant tout je vous remercie d'avance pour les réponses que vous pourrez m'apporter.

Après avoir installer css, fait les décryptages et les mises a jours, je lance le jeu et la le message suivant apparait "la derniere version de directx(r) est nécéssaire pour pouvoir jouer à counter strike source" il m'indique un lien ou téléchargez les dernieres MAJ de directx.......je telecharge puis après avoir débuter l'installation j' ai cet autre message d'erreur qui apparait "Une erreur système s'est produite. Consultez les fichiers DXerror.log et DirectX.log situer dans le dossier windows pour déterminer le problème".

Ce que je ne comprends pas c'est que je peux lancer world of warcraft sans problème et pas counter strike....


Voici le contenu de mon fichier directx.log
