Everytime I attempt to launch a non custom summoners rift match the application crashes and continues to do so on reconnect attempts. I can play TTL just fine and howling abyss. Please help!

Now I can't even launch the client due to the pvp kernel

I've checked everything so far nothing seems to work. Just wondering if any has found a fix

To fix the kernal thing, I always go to the Task Manager, find a program called LoLLauncher and end the process. That's always worked for me.

I always imagined the Kernal thing was a popcorn related joke. /sidetrack

I assume you've tried the repair, then uninstall-reinstall with computer restarts between, with no success?

Hrm... I don't wanna say it, but restore your computer to factory defualt if you know how to safetly to rule out any corrupted software that is core to your system.
