WotLK The game didin't work "Patch Required"

[SamAgain]

Hello guys, i have a little bit problem.
Sry if I speaking bad, im french ^^'

So, my launcher it's okay.
I can login.
But in the time of the connect, the game search one uptade, and at the finish he speaking to me for :

Patch Required
"Press the restart button below to exit World of Warcraft and download the patch."

When I press restart, the launcher says :

"Failed to apply patch. Please try again later. If this problem persists you may need to reinstall or contact technical support."

So, do you have an idea for helping me ? :)
Sorry for disturbing.
