My modpack is not launching

[Krystof11cze]

Hello,

I have started working on my Technic Launcher modpack. I have downloaded all mods I wanted and moved them into mods directory in my Minecraft folder. When I launched my Minecraft, created the world. Everything worked fine. Then, I have created four folders. mods, config, bin and Flans (From Flans mod). Then I moved it in a zip file and uploaded it on Dropbox. I have copied the url and pasted it in to modpack. In Technic Launcher, I downloaded my modpack. But when I launch it, Technic Launcher disappear for a second and then appear again. Do you know what could be the problem?

My modpack: http://www.technicpack.net/modpack/better-then-before.772920

Modpack in Dropbox: https://www.dropbox.com/s/kcrn3q2r88d3k7x/BetterThenBefore.zip?dl=0

Thanks, Krystof11cze

Make sure your tekkit modpack account has the right version of Minecaft selected (1.7.10) for your pack. You are getting a "Binary Mismatch" error, that is often the cause.
