5.4 Update screwed league!

I need help . After the 5.4 update my LoL won't run a single game at all. Every time I join a game or create a custom it keeps on having firewall problem. Disabling it---still same problem. Restarting computer yet problem doesn't go. My last game as Nautilus....I've been there the entire time trying to reconnect but it just didn't and now I ended up with a LEAVE. I never leave game and I don't deserve this either. I want this problem to be fixed as soon as possible. Or like League is gonna lose a player or else. I restarted my laptop like 7x just to join my last game and I couldn't. Luckily me team isn't reporting me cause they just won a 4v5 game and they all know about this firewall problem.

Every time I try to reconnect I get this :- http://gyazo.com/1df6f4e348b59861aebd60d9f523534a ....after like 2mins but yea. I didn't take screenshot of last attempt.

HELP PLEASE RIOT! And instead of a leave for my last game , I deserve a loss prevented please!

Thank you, Yuuki Yagami- NA
