Cant enter game

why is there always something when new patch goes live???
i cant even enter game from battle net , i just click start game on app and nothing happend
FFS
AND WHAT? im supposed wait till toomorow to get this fixed up???

Open task manager and search of instances of wow.exe running and use the end process option to kill them.

Very occasionally the wow process can get stuck trying to start up which will prevent the game from opening no matter how much you try.

You are not alone with this problem. There are other posts in EU and US servers explaining this issue.

After cliking START in Battle.net, the screen goes black showing the “World of Warcraft” program bar flashing at the top of the screen, and the mouse pointer has changed to the gauntlet. The sound is still playing. In this screen, if you press Enter key several times, then it goes to the static loading screen with loading progress bar. But once it finishes loading and goes into the game, then it’s back to the black screen again.

Although this problem is probably related to Windows 7, it is also reported by other user with Windows 10.

I think I’ve come up with a possible solution. Delete the Retail > WTF > Config.wtf file (or make a backup so you can remember what values you had configured previously). Remember that this file only has the general configuration values (graphics, sound…), not the custom ones for each character or the addons configuration. After deleting the file, start the game normally. Of course, all graphics options will have been reset to default values. Reconfigure the game. Change the graphics options one by one to see which one triggers the error in your case.

In my case, the option that triggers the error is anti-aliasing > image-based techniques > CMAA. You can test it to see if this is your case, since I use DX11 and render scale of 150%. I don’t know if the problem also happens with DX12 or other options.
