If you are having issues with accessing Battle.net multiplayer mode due to missing menu text then there is a possibility that a third party application is interfering with the game(for example: LogiOptions.exe, part of Logitech drivers for keyboards/mice). The potential workaround for this problem would be to launch the game in 'clean boot' mode, you can find instructions HERE.
Win8\10 actually do not allow real "clean boot"... or any other mode than normal one. And you must use third party tools to edit boot options and autostartup-programs list. It not work as on screenshots from Microsoft: Task Manager show only few programs in Startup Tab.
Just check process list (advanced Tab, nor very first screen of TM) in Task Manager for something like Geforce Experience exe of LogiOptions.exe after normal Windows boot.
