The Game doesn't allow to start playing

No matter how many times, reopening the game has no effect; the game loads all what it wants taking no much time, perfect, but then in the initial screen where you can visualize the battlenet login and some other button options, the server option with the name never appears, and thus tapping to start playing doesn't work, this for long time with no direct reason, and even if left the screen for sometime to expect any change by loading occult data or anything at all, still the server option doesn't show up
