Client has crashed during champion select 4 times causing me to lose LP and even a promo............

Is this just a bug with my client or has this happened to anyone else.... its actually really starting to tilt me because it happens every other ranked game and it makes me lose more and more lp everytime. When my client crashes I open it back up and log back in and im not in the champ select anymore. When im duo with a friend he stays in the champion select until it kicks him because it says i did not ban or choose a champion. One time when he was still in champion select I tried to queue up again and it immediately kicked him from the champion select and on my screen a notification popped up saying something like "there was a server error and the group has been disbanded".... and then I lost more lp... if its a server error why do i have to get punished for it://///////////// Do u guys think I should just try reinstalling my client... or is there something else i can do cause reinstalling takes foreverrrrrrrrrr I also currently have a 30 MIN QUEUE AND THATS EVEN MORE TILTING LOL
