Won't load into game

I can launch the client just fine. It updates and everything works. I enter queue and everything works. Champ select works fine, but when the countdown reaches zero, the champ select window closes and then nothing happens. I never actually load into the game. I've tried reinstalling, tried running the repair but nothing has worked so far. I don't get a pop-up saying the client crashed, or there are firewall problems (though I have tried disabling the firewall and it didn't change anything) I don't know what else to do. Help me rito
