Call of Duty 4

Bonjour,

J'ai installé Call of Duty 4, l'installation ne présente aucuns problème, et lorsque j'essaye de lancer le mode solo, un mot d'erreur apparait:

"Fastfile for zone 'ui' is corrupt or unreadable."

Je vous copie ce qui est écrit dans la console:

Quelqu'un peut m'aider? C'est un peu embettant de ne pas pouvoir y jouer :(

Merci à tous ceux qui prendront un petit moment pour m'aider =)
