I know this is a late response, but i had that issue aswell, it is caused from using java 8 when you need to run java 7, if you downloaded it after the launcher gave you the error you still will need to redirect the patch the ftb launcher takes, you can edit that in the optionsYep basically it tries to launch and all of a sudden it goes back to the launcher :S
This looks like a very fun pack! Trying it now.
