Crash upon trying to load any map

I decided to give the mod a go after all the updates, and I tried loading into the new survival map. It loads, I press start, and after hanging a bit it crashes. Alright, lets try the campaign then. Loads the OSA screen, press start, repeat from earlier. I do a check to see if any files are missing; nada. This is a fresh install too, so I don't really understand what's wrong. Any ideas?
