Pixelmon Generations not launching

[PewDiePie!]

So I have downloaded Pixelmon generations official, I have allocated 2GB of Memory to it. When i click play, the launcher goes away for a while then reappears again and the mod pack doesn't launch. New to asking for help on forums, please inform me if i need to give more details ^^

You need to ask help from Pixelmon devs. We don't support that modpack here.

If you have an issue with Technic's official packs, do tell
