Let me know what information you need and I'll happily provide it.
In both Desura and Steam I've deleted the game and reinstalled it. No other mods. I then use the Modding Tools to install X:CE .31 +settings + balance and it always crashes out. .30 works like a charm, though I do have an issue with it where the combat loading screen won't go past the 3rd tick when attacking an alien base but that's a separate issue.
