Continous random CTDs

[carthage_supreme]

Ever since i installed rtw with eb a week ago it has been continously crashing. Usually it happens after playing 10mins , but sometimes it crashes after playing an hour. The CTD's dont appear to me to have any specific patterns , I get ctds during battles , after battles , in middle of the campaign or during AI turn.
And it's been going on in every single campagin ive been playing.



Here is the save file from my lastest casse campaign.

Please help me , this constant annoyance is going to make me go nuts.

(Im using vista by the way, could that be the reason?, since vista is not very compatible with older games.)

Any help/tip would be appreciated.
