nothing fixed the client!

so i had the problem wit the client as well, but EVERYTHING i tried failed to resolve this issue. I've ran full repair, ran hex-tech repair tool, reinstalled the game(both with and without deleting league), and ABSOLUTELY NOTHING WORKS! I've tried support but that was useless with 2-3 year old problems that don't pertain to my predicament. so RIOT IF YOU'RE READING THIS, FIX YOUR GODDAMN VIDEO GAME AND DO NOT FUCK WITH YOUR CLIENT AGAIN!!!!!
