Client crashes

Since the beginning of Ranked Season 7 I've had the issue you've posted about with the game client not joining games properly, but I've also experience a few other bugs and crashes that have been causing problems in my daily gaming. Often when I try to open the client it prompts me to update back to a previous build, then wont allow me to join a game, re updates and works okay for a few hours, I'll get the crash where it doesnt join the game and I simply close and re-open which is fine no big deal easy solve, but then begins crashing in champion selection lobby, which leads quickly to a 30 min que ban, (which by the way, 6 mins for the first time 30 minutes the second... that's 1/48th my day how does that seem like a fair ban time?) so i close my client re-open log back in try to play some customs which it will allow me to do just fine. But I've been having this issue since 1:08am PST 12-11-16 where it will say that I'm having trouble connecting to the servers and to check the server's status. Which of course I do, and of course it is always fine and online. I've checked my internet to be sure that is not an issue. my provider reports no issue, i test my hardware it reports no issue. I've just been having non-stop issues on the client and joining games and in champion lobbies that most of the time i've spent logged in has been either fighting with the client to let me play, or waiting in que times to join a champion select to get kicked due to some client crash and then have to sit around and wait 30 minutes to have it happen again..

Sorry to take up your time, FutureShamann..
