Client Crashing

I've been having SO MANY problems lately with the client crashing. It has crashed three times now (in as many days) after I press "accept". Seriously? And it's counting as a DODGE because there's no way for me to get back into the game that started but I NEVER JOINED. I'm sitting, again, on another 30m wait because Riot messed up. Really Rito?!

Plus, lately, I've had several games crash (and send bug reports) after they've started.

What's going on? I didn't have problems for months, and now they're all over the place again. Guys... guys... cmon.
