Bugsplat crash every time I join a game?

I haven't ever had an issue in the past connecting to league. I had to go away for a few weeks / months on military service and now, when i come back, every single time i start a game i crash to desktop with a bugsplat. I've tried uninstalling and reinstalling, i've tried updating all my drivers, tried updating directx, tried everything on the support page regarding crashes. Hasn't helped, i'm still seeing a bugsplat every time i start to load a game.

I'm not sure what to do here. I'd like the chance to play League with my fiancee and friends before i need to leave again, but at this rate they're just getting more fed up with me crashing than they are interested in me trying to play.

Help me rito-dev-kenobi; you're my only hope!
