Left click attack move between servers

Hello!

So I installed the left click attack move function a few months ago now: https://www.reddit.com/r/leagueoflegends/comments/1bo2nk/guide_to_easy_kiting_left_click_attack

I have really been liking it, but unfortunately when I play on another server, it doesn't work there and I have to use right click, and when I go back to my home server, I sometimes start using right click, which really annoys me, because I end messing up everything. Can somebody tell me how could I install the left click move to another servers if there is a way?
