How to fix your input file!

So i recently messed up my Input.ini and could not figure out how to fix it, but i found out so i am here to share with you. You do not need to uninstall or anything like that, just go into your C:Riot Games/League Of Legends (or wherever yours is) and delete the Config folder. Now just start League and it will apply a very small patch. Then go into a custom match and go into your settings and click restore defaults, it should already be default but just to make sure. Now it should be all good, and your bindings should be back to normal. Hope this helps!

Edit: this resets all setting, so make sure you know what your video settings are, audio etc.
