Riot client problems

So i just got that 5 game matchmaking low priority thing due to random riot client bug splats. I would like to thank riot for punishing me for there mistakes and i would like riot to fix the problem. since patch 5.2 my client wont start it will randomly close my client and then not let me go into loading screen.. I am a paying customer who has paid a lot due to my love for this game. The fact that i get repaid with a punishment because of random client problems is unacceptable. Does anyone have a solution to this problem? The problem isnt constant and it makes me think i have fixed the problem after a few games but then when im one or two games into ranked, oh bug splat and then it wont let me go back into loading screen. I went 2-8 in provisional due to this happening 6 times only which one of the games where i went remotely neutral and wasn't winning when it happened. I don't know what to do other than to stop playing a game i once called a hobby. Thank you Riot.
