Game Crashes Every Time!

Ok, so i recently installed patch 5.4, and I was so excited to go check out all the changes and such, but i noticed a reoccurring problem. Every time i get into game, and we are in the loading screen, as soon as im about to head in the game, my game force quits, and im back to the home page, and it says that the game has crashed, please reconnect to the game. I have gotten this message for 2 days in a row and im getting worried. i have already tried reinstalling, but that did not work. if anyone has any suggestions or solutions please let me know! i really hope i dont get a temporary ban for leaving, because its not my fault my client decides to quit every time i get into a match. may i also mention my ping has been maintained to run 50 or below, so it is fair. im not sure if this problem is a direct correlation to the new update, but anything that could shed some light on this matter would be greatly appreciated!
