Just clicked on my WOW icon and left for a while. When returned its downloaded and installed new patch 2.1.3 (6898). My WOW is not working any more (stupid me ). Now i install all again will see if it works. Guys did anyone hade same problem or just me?

Hum... no problem with mine
But... on the EU official web site I don't even see this new up-date of yours, they are still displaying the patch note of the 2.1.2

Hello,

Yesterday, when I connected with my French version of WoW I also saw the message saying that European servers were updating to version 2.1.3. But as in my realmlist is connecting to china I was not affected ;-)

yes me too rigth now... I open my french client and he try to download the new verison.... dam it, i set the realm same as before, i dunno why he till try to get the new version....
after what ? where we could change that ? it's downloading... But througth the chinese sevrer ? how its possible ? no way, if i stop it, i can't play anymore, i must wait the end of the proces but my firewal ask me if i accept to lauch the wow downloader, sure i said no, then after cloase and open the game many time it's working now... Strange ! It downloaded the wow downloader througth the chinese server ...CN1grunt etc... Sure there is an other folder with the european address somewhere else, we should find and erase it, that's the mess !
