Kind of complicated... you can go to youtube? I tried to, but it just deleted all my progress. But it's worth a try, right? So first, download WinRAR. Then go to "run" in the start menu, type in %appdata% and click .minecraft . Then go to the "bin" file right click "minecraft" then cilck "Open with" and choose winRAR. then... JUST WATCH A VIDEO IM SORRY ILL MESS YOU UP ITS TOO COMPLICATED IM SORRY!!!!
