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\Aaron\AppData\Roaming\.minecraft\libraries\net\sf\jopt-simple\jopt-simple\4.5\jopt-simple-4.5.jar Exists: File

this is the exact error im getting. i tried following the directions in this youtube video, launcher is updated since the video was made but i feel like it was faily simple. when i go to launch with forge in the mincraft launcher i get that message:

i can download that file but i dont know where to put it or if i even need it.

i also updated my java and that did not work either and same message occurs.

thanks!
