I keep on trying to fix this one modpack for my brother, "Lets see how this ends..." and it keeps displaying this error message when it finishes installing: Error unzipping a file for the following pack: Lets see how this ends... Error extracting file modpack.jar Please consult the modpack author. My forge version is: 14.23.5.2838 Any info is helpful. Here is the download link: https://www.dropbox.com/s/mw1drjkxyz9rr1q/Completely%20and%20Utterly%20New.zip?dl=1
