Crash on turn 52, with SS 6.4

[Draksan]

Hello,
I have a big problem, my game crash on turn 52, during the rebel's turn. I play the Holy Roman Empire, on SS 6.4.
I installed the SS 6.4 because of the bug "turn 51" on SS 6.3, but I can only go 1 turn after before bug again !
I tried a lot of things, like hotfix and patches, but there's no way, my game ALWAY crash at rebel's turn 52. I also tried to instal the Meneth Compandium, but nothing happened.
Maybe that's because I'm bad in informatic, but nothing work I really want to continue my campain on this mod so help meeeeeee

Sorry for my bad english :3
