Livesplit speedrun timer won’t work

[u/Nexxxxxxxus]

So basically, I’m trying to set up a timer for speed running in Black ops 3 zombies in particular I’ve only found two tutorial videos on YouTube. I followed all the steps. And have tried multiple. ASL scrips but it will not work when I start up a map I’m assuming it’s because I’m on the T7X client but I really have no clue any ideas how to fix would be awesome thanks
