Game crashes as soon as I enter ranked game

My game was working perfectly fine after the patch until I got to my last two games in my series to get to Gold V I was 2W-1L going in and I q'd for a ranked. I got into the pick/ban phase and could access chat. Only nothing ever happened, I could chat at first and people responded, but then it just froze, I could see no bans occurring and after about 30 seconds people stopped responding in chat. I got a connection error message hit OK but I just stayed in the pick/ban phase no champions banned none picked for 5+ mins. Finally I closed the game (didn't want to because of series).

Logged back in and was nervous about what had happened, so played a team builder game or two, then a custom. Both worked fine so I Q'd up for ranked again. This time I after my game was found and I accepted the invite the entire game simply closed, no error message, nada. Logged back on again to see that it counted as a loss in my series... I was up 2-1 and lost two in a row to freaking client crashes please fix!!
