Custom Modpack Not Working Custom Modpack Not Working

[doctor2212]

Hello all, my custom 1.7.10 modpack crashes when I try to play it, it loads up the Minecraft window and then just does back to the Technic Launcher. I have no idea what's wrong, so any help in what it is that's making it crash and how I can fix it would be greatly appreciated.

 

Here is the latest 'log' file:

Here is the latest 'crash report':

Also, here is the platform URL link for the custom modpack (it's private and hidden so don't distribute please, thank you!):

All help will be greatly appreciated, thank you!

The current versions of Calclavia's mods do not work together. This is a common problem with his mods. You will need to follow up with the mod author, possibly in their IRC channel, in order to find which versions of the mods should be used together.
