I have had so many problems with modpack things like Technic and now this, too. Every time I load up a modpack, it downloads, even though the files are in an obvious spot. Then, FML says it's "Setting Up My MineCraft Environment" and stays at 0% forever. It did that for DireWolf and Mindcrack, and Brony modpack came up with a white screen. I would really appreciate help, because I would really like to play something like Mindcrack. Thanks. Oh, and there are no errors in the log.
