online few minutes and Error!

Hello, i decided to ask help from here, because ingame no1 has few minutes to explain whatsup and too lazy to log in for few minutes 10x.
So, i downloaded WoW 4.3.4 from ***** website on my PC, first i had problems with logging in (antivirus, SOLVED) and now i have problems with playing wow. I log in, everything is good, after few minutes, maximum 5minutes i get ERROR like this https://gyazo.com/0c66fcb0f38eab2911ac062cbeecf027 i've unchecked exe file, folders, deleted cache etc. And still got the error.
pls any smart person, help :) Thx

Well, I would suggest you use our launcher and not someone elses since we don't know much about it. Also, checkout this thread on solving #134 errors.
