Horizons and DW20 Pack download, Don't Start

[Failurebot]

So for the past couple days, I have been trying to play the new Horizons and DireWolf20 packs. My problem here is that the packs will download, bit then my launcher freezes up and the game doesn't start. This is the link to my console's log from the moment I clicked start, and downloaded the DW20 pack, posted on pastebin, http://pastebin.com/vfSsLLyL
Maybe this will help, but any and all assistance would be awesome, I really would love to play these new packs.
