BLACK SCREEN AFTER HITTING "ACCEPT"

This has to be the most frustrating part about League. I am playing my ass off to get to the next level, my client blacks out not ONCE, but TWICE in the same day, after UPDATING the client, oh btw, that was SUGGESTED by RIOT, to find out that I lost LP and have to wait for 30 MINS for something that I didn't do...!!!! lost 2 Ranked Games because of this software ERROR.

RIOT you've got to find a way to accommodate to the players that go through this...you cant just expect players to waste more time NOT knowing when that error is going to happen again...!!!

I get bugs will always be part of my life when it comes to anything computing, but you have to find a way to take care of this. Ive been a loyal player for the last 3 yrs, this isnt how you treat us.

Who can help me or reach out to me so I know that I am even waisting my time typing this msg up.

Thanks, A LoL Player!
