I am trying to launch SkyFactory 3 so I get to the launcher and when I launch it, it either launches and immediately closes or gives me this message:
"Failed to download file, the file contents differ from what was expected.
Filename on disk: jopt-simple-4.6.jar
I have no idea what this means or how to fix it. I've looked it up, I've uninstalled and reinstalled, and I've also "repaired" the files. If you know how to fix any help is appreciated thanks.
I also included picture
Edit: i am running through twitch if it help
