New Client Bug

Hello, i hope you will answer me fast and corectly, because im getting mad. So after the new client has been added i dont see anything on it. What that's mean ? That's mean i dont see my nickname in the logging screen, my password too, when i logg in i dont see my friends, i dont see runes and masteries pages when I join a game lobby. Now i reinstall all the game, and if it doesn't work i hope u give me a answer how to fix it, because i cant play normaly with this problem. Thank you.
