Hi, i buyed a steam account with bo2 well i think it must be an russian account because the game wont start when i put it on english. i tried to change it to polish didnt worked to, i uninstalled the game no chance. i cant find anything on youtube or on any other forum. btw i can run singleplayer and multipaly but it needs to be russian. when i run plutonium it doesnt work.
