I can't open my Client ...

So I'm not that kind of person who "cries" when they have a problem. I face my own problem OR I ask people for help , calmly. So guys help me on this . I sent a ticket to Riot but they didn't reply yet and I wanna play LoL A.S.A.P .. I click the LoL Icon and the 'League of Legends' Badge just shows up in the middle of my screens and after that .. nothing .... I wanna play LoL , please ... help.
