[CRASH] I Cannot Load A Match

Ever since the Snowdown update, I haven't been able to load up a Snowdown match. My launcher and client work just fine, but when everyone's loaded up and the match should load up, nothing happens. It just disappears. I check my active programs, and it has nothing. I try to re-launch the client and launcher, but it says "Another program of this is running. Do you wish to terminate it?" When it loads back up, and I log back in, it says "Reconnect", leading me back to the whole problem of not loading. I even restarted my computer, and that didn't help anything.

I've tried this for two days now, and it's doing the same thing as before.
