Crash while trying to load up

[Grimm Spector]

Getting a crash with mods, not sure if I'm having a low memory issue or not. Pretty sure I was when trying to run it on 32 bit, but when running on 64 bit that really shouldn't be an issue, and I'm getting the crash on there too, I tried removing a few mods, and get as far as the load screen with the little solar system icon in the lower right corner before it dies, sometimes it crashes without a message, sometimes with, but I'm having trouble decoding this log. It's pretty big so here's a pastebin.

Any ideas?? Thanks!
