I have no lol_air_client folder?

I'm trying to switch off my in game profanity filter because its bugged and I've done it before so I know I can but then I recently deleted League because of a bug and now I have no lol_air_client folder which is needed? Here's the tutorial on how to do it "C:\Riot Games\League of Legends\RADS\projects\lol_air_client\releases(lat est version)\deploy\preferences

Open up the shared(character name).PROPERTIES file up with Notepad

It should say:

[Chat] EnableChatFilter=1

MAKE SURE YOUR LEAGUE OF LEGENDS CLIENT IS CLOSED WHEN YOU DO THIS!

Just change the 1 to a 0. Hit Ctrl+S to save it. Go in game and enjoy your curse words."
