    So I am trying to play FTB Infinity Evolved but it won't launch, I am currently using the twitch app to launch the modpacks but when I try to launch FTB Infinity evolved I get the launcher open but when I click play I get an error.
    Failed to download file, the file contents differ from what was expected.
    Name: jopt-simple-4.5.jar
    URL: https://libraries.minecraft.net/net/sf/jopt-simple/jopt-simple/4.5/jopt-simple-4.5.jar
    Filename on disk: jopt-simple-4.5.jar
    Path: C:\Users\(me)\Twitch\Minecraft\Install\libraries\net\sf\jopt-simple\jopt-simple\4.5\jopt-simple-4.5.jar
    Exists: File
    Can I maybe get some in resolving this issue?
