Can't get into match, never loads

I was in Team Builder, and when the match started I was stuck in client. My status showed "In Game." I tried restarting the client, but whenever I click "Reconnect," nothing loads. Even if I wait for a while, nothing happens. Recently, my computer displayed an error message about not being able to start Windows. I think this might have something to do with it. Reinstalling might work, but the game will probably end before it finishes downloading, leading to punishment by LeaverBuster.
