I'm not sure what's causing the crash, but it looks like you're using a really old version of the mod from 2014 for some reason, which doesn't even require the llibrary you're using. Do you know where you got that version of the mod from?

I'd suggest you update to the latest version from here if you can (which might fix the crashes), but the 7.0 update of the mod changes a whole bunch of stuff so some of your mod blocks, mobs, and items would disappear/change.
