As soon as I launch League of Legends I get the following error:
PvP.net Patcher Kernel has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is avilable.
I was able to launch the game a few days ago and I haven't changed a thing. I haven't even played because I am currently banned. I just launch it sometimes to check for patches.
Seeing as I changed NOTHING, I would assume the issue is on Riot's side.
Here's a picture of the error: http://s14.directupload.net/images/121103/eqlncnkh.png
EDIT: Just to be clear, I was able to start the launcher after installing Windows 8, this has nothing to do with it.
