Required steps for the mod to work:

1. Add -debug to STEAM LAUNCH OPTIONS (NOT IN PARADOX LAUNCHER)
   
2. Disable ALL DLC
   
3. Switch to dx9 or OpenGL Rendering

If you have done all of the above steps and it's still crashing:
Try increasing your pagefile or swap file to 20GB+ (aka 20000 in windows.) If you don't know how to do it, look it up. it's not that hard to do.

Also, if the game is "freezing," just be patient and don't click the screen while it's loading. Go make lunch or some coffee/tea. It's probably going to take a while on the first load. It's only "Crashed" if the game closes and spits out a crash log or "report to paradox" message.

Good luck gamers.
