Frosty Mod Manager broke my Game

So last night I saw a video on Battlefront 2 mods. I follow the tutorial because I thought it looked cool. Mods ended up not working. "No big deal" I thought, and I deleted frosty, and the files it added to Battlefront 2. I then try relaunching and and.... nothing... I try again, EA app closes, then opens again with nothing loaded. I signed out and signed in again, still nothing. I even reinstalled the dang game! Still nothing! Please help me, I love this game and I've tried everything, I'm outta ideas.
