Horizons pack won't launch

[Jordandm7]

Hey guys,
After many times of deleting the pack, launcher and re-installing the Horizons pack still won't seem to launch.
I have 16gb of ram and 8 of it dedicated to FTB, not too sure why only this pack wont launch, no popup error messages, I just click play, and then the launcher and the console close.
If you have any way of helping, please let me know.
Thanks,
Jonathan

From the looks of that crash report. It looks like the mods in the pack are trying to run a version of minecraft that is not supported. Have you tried to completely reinstall feed the beast? When you have multiple launchers and multiple directories it can cause problems. Try this http://desk.feed-the-beast.com/index.php?/Knowledgebase/Article/View/9/0/basic-troubleshooting

Change the folder destination in the options. I was stressing over this problem too!
