Client wouldn't let me load into my game and forced me to update while trying to load back in.

I was trying to play an ARURF game when the load screen popped up and went black. The only way to fix it was to restart my PC, so i did. Then the client decided that it needed to update while my game was going on. This update for 0.6mb took way to long and just stood still once it had downloaded. I now have a 20 minute que timer since this has been a reoccurring thing. I always have problems loading back in when the client fails to work properly and i have been receiving so many leave buster bans.
