I'm having a problem installing this.
Downloaded it, extracted it, copied the LoL folder, replaced the vanilla LoL folder with it, copied my UI resolution, renamed the UI resolution file to HudResolutionDefaults.ini, went into custom matches multiple times to make sure I had the correct in-game settings/resolution and still nothings changed
EDIT: I was using the new LoL launcher. But now I don't have a UI. The health bars changed, but that's it. I made sure I changed all the ingame settings again.
