My Problems started yesterday when I was unable to play CoD because the Game reported that it needs to update in order to start. Since there was no update, i re-installed the game several times without success. As a last try, i deinstalled the battle.net app, cleared all the traces of the app but since i am unable to reinstall it due to an BLZBNTBTS00000029 Error.
The hosts of the patchserver can be resolved from my machine (using WinMRT) . I have no idea what to do anymore
