Description of Problem:

So my little sister really wanted this mod so she searched up some janky fake mod pack on the technic website. However, after opening it up in the launcher, it just played vanilla minecraft. However, I have one problem. The little "-" minus sign under the mod pack doesn't appear, and the folders for the mod packs will delete, but re- download and appear on the technic launcher. I really need help on this since it's just stuck there. How do I remove a mod pack? (I'm a huge noob when it comes to computers so it's probably just some stupid thing I can't figure out) Please comment if i left out crucial details
