Error loop: wrong password window > click here or OK > restart client > wrong password window >

I accidentally did mistype my password in the new white updated logging screen, the username and realm were correct. After that I've got the message: "Username or password is incorrect. Please try logging in again. If you have forgotten your password, click here.". I've tried to click "here" but nothing happened, neither any window for the password reset popped out. Then I tried to click "OK" down below, what happened is that my client shat down completely, and does not let me try to log in again. No process of "League of Legends" is running in task manager, and I even tried to restart my PC several times. Nothing is fixing the loop of the wrong password bug screen, me pressing OK or here, me opening the client again, and then the same error again and again and again... I'm helpless you guys.
