    I'm having a problem launching, FTB revelation, from the Twitch client. when pressing play, it shows a download bar, and then i get this:

    Failed to download file, the file contents differ from what was expected.
    Name: jna-4.4.0.jar
    URL: ....libraries.minecraft....
    Filename on disk: jna-4.4.0.jar
    Path: C:\Users\xxxx\Twitch\Minecraft\Install\libraries\net\java\dev\jna\jna\4.4.0\jna-4.4.0.jar
    Exists: File
