EB start to ctd during my second campaign

Hello everybody,
first of all congratulions, this mod is fantastic.
I have this problem since a week and I didn't found a solution in other threads:
I've intalled EB on a RTW gold edition steam version, first campaign works simply perfect, I played with Hayasdan for I don't know how many turns and rarely ctd, nothing to be worried about.
Now I start a new campaign with romans, I am at 231 BC but from 10-20 turns the game ctd every 2or 3 battle. It start crashing loading the battle, then crashing also after the battle and now sometimes ctd happens in the map mode, but rarely.
Someone could help me please? I've 1.2 and all the patch and fixes (including the enviroment patch).
Thanks for your time and again very good job with EB
