I can't apply patch

Hello,
I played in the morning, i stopped, and now i want to reconnect BUT it needs a patch. After the game wants to restart, it doesnt work and show the message "Failed to apply patch. Please try again later. If this probel persists you may need to reinstall or contact technical support." I turned off my antivirus but didnt work.
Thanks for Help

Don't start the game from the Launcher.exe. User WoW.exe and log-in with your username and not email adress.

It works, thanks a lot !
