Apparently you need 2 flan folders, all other videos I see of installing flan requires 2 folders with the same mods inside. I moved the files into the proper position (thank you :D), and scanned the mods using AVG, but from now on I will only use the sites you recommended. How did you know what site I downloaded it from though?
But now when I launch the modpack it won't even launch Minecraft, the launcher just flashes for a second and goes back to normal.
