I find it hard to escape silver...

Every time I am about to climb to a higher division I get lolclient.exe has stopped working and I dodge the game during the selection screen and lose LP or part of my series. Other times I enter the champion selection screen and get "Game In Progress" with the selection music playing in the background. I hear bans going out and when it's finally my turn to pick (I know because of the pick sound whenever it's your turn to pick) the entire client still says "Game In Progress" and since I can't pick, I fail to select a champion and the game dodges I lose LP or one of my series.
