Client issues

So its been a month or so that my client has been bugging out. I launch it like usual and then I login like eveyone else. Theres nothing wrong with it so far but when im in a game and when I win or lose I have to click "continue" and after I do that my client doesnt launch back up so i have to relogin and do it over and over for every game. I'm not so sure if i'm the only one but its kinda bothering me now. I also try to uninstall it and reinstall it but league doesn't show up in my contro panel neither so i really need help how to fix this.
