Someone help pls

I have been trying to play League all day and it feels impossible. First, I got kicked from a game and got bugsplat and it wouldn't work after that so I had to redownload (ive been banned for that before). I was able to play one game before I started getting kicked again without bugsplat this time and the client telling me that my data was corrupted and that it needed to repair, which has happened twice. I was hoping that someone could help me before I get banned over something that feel is not in my control.
