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?

Oh I'm a dumbass, found out why: My anti-virus was thinking the game wanting to make saves was something weird. Disregard the thread.

That's not dumbass. Others might find that your experience solves their issue.
