Can't play It. Is there a link with the game fixed for It to download?

I literally bought the game on Steam and the Textures didn't load, I couldn't even play the First mission. Tried to fix It with every mod possible, filled my PC with dozens of sketchy files and still had the same issue, even though the mod fixes were loading. Ended up refunding the game after 5h of frustration literally trying tô get It to work. Is there a pirate version with the fixed game? I tried my Very best to make It work, but I'm not gonna stay trying If I have the slightest chance of never working and losing 79 reais (about 15ish dollars).
