problems patching

Ok, here's my problem:

im trying to download and install the latest patch, but at "downloading updating tools" (or something like, that, my game is in french). It jam at 10-15% and my luncher shut down. Then im waiting to see if something happen, nothing. So i restart my luncher, it start over and same problem, until i cant open my luncher at all...

Can someone tell me how to repair this annoying problem or give me a link for the latest patch, in french. (frFR),

Thanks.|||Go into your WoW folder and find the program "repair.exe". Run that and you should be fine.

I had the same problem and this fixed it.
