Fatal Crash

So I played fine on League yesterday however when I got on today I tried to join a match and got a huge fatal crash, I tried reconnecting but I just kept getting a fatal crash, the match ended rather quickly because I wasn't able to connect into the game, I tried another match but got the same problem, so I tried Aram to see if there was an issue with summoners rift but the same thing happened and I'm not sure what to do other than reinstall league.
