Mimic

Agh I don't know why it still isn't working! It works the first time that I Ioad it, as long as I have never played it before, but whenever I try to access, for example Hexxit, a second time, it won't get past the FML then white screen. (I actually got through to Hexxit twice instead of the usual just once today) I feel like the only solution is to never exit whatever modpack I'm playing? Is this maybe a problem where I just need to keep loading and reloading the page until it works? Could I be doing something wrong?

Now if you could explain how to do this: and save it with the extension ".command". Put it in the same folder as technic-launcher.jar. You need to mark it as executable first using Terminal: like I'm five, that would be great
