Decimation wont open

[ClipityBipity]

So, for 2 days ive been browsing threads to see if anyone is having the same problem as me, and a few people are, and i followed those threads as much as i could, but i barely know anything about files and stuff, anyways, ive been trying to open the decimation pack and it opens, goes to about 1/7 in the mojang loading screen then abruptly closes, if anyone can help me out with this i would really appreciate it. 

Side note: this is the only modpack this happens with, i can open any other modpack just fine.
Heres the patebin, but i have no idea what youre looking for, so i just copied half of it. im sorry if its a hassle to look through
Thank you
