How to I change AI?

[Hider]

When I open the beta launcher it gives me some maps with AI included I can choose. And it uses Starcrack 7.0 as default. I have tried downloading some AIs, but I dont know where to place the file, and how can I see if I am succesfully using an AI?

you have to place the AI you've downloaded into the folder: mods > liberty.scmod

the file you will be replacing is called: base.sc2data

So I downloaded a file and placed it there. However it still shows the starcrack 7.0 standard file over the change the AI folder. Am I doing something wrong?
