Technic won't launch any modpacks, Help!

So when I go to launch a new modpack it gets to 'loading assets' and then just stops and does nothing. I have 64 bit java and 12GB ram and I cant figure it out.

 

Here's a link to my logs: https://pastebin.com/VnS9Z80h

Sigh. Stop trying to allocate 8 GB or 10 GB RAM if you don't have it available.

Oh ok, thanks man, my PC has 12GB and I allocate 10ish to most games and it works fine (even different modpack launchers). Wierd but I lowered the memory and its working!
