I want to play a modpack that is only available for 1.10.2, so I downloaded the stable and recommended version of forge and installed the profiles to my Launcher. Now when starting one of those I keep getting this error on first try (after pressing play). The second time, the Launcher crashes. Failed to download file, the file contents differ from what was expected.
