To be absolutely clear on this point:
The Eb-team supports EB1 only for RomeTW.exe not for the addons, these are minimods created by people not afflicted with the team.

Switching to BI may help you, however in most times the CTD's are engine related, take a good look into the frequent issues and especially in the section about crashes.

IIRC RTW-->BI is completely safe, RTW/BI-->Alex may require additional files (check the submod.forum).
