CTD in Family Tree

[KnightoftheNine]

I have a strange problem.
Everytime I want to take a look at my Family Tree the game crashes and the system log just says "[system.rpt] [error] Medieval 2: Total War encountered an unspecified error and will now exit".
Somehow this only happens when i scroll at the right side of my Family Tree near my heir.
Maybe somebody could test the save and check the tree?
I use the early era campaign, permanent watchtowers, that mod that makes conquered cities harder to hold, savage AI and heir crown as England.
Here is the savefile: http://speedy.sh/JqA9C/Family-Tree.sav

Since nobody seems to know a solution here, could at least someone test the savegame? THe Crown of my Empire now "swiched" to the over side of the family tree and now this part of the tree is also affected of the problem explained in my first post.
Could please someone check, if this problem appears for others as well?

That is a bad install, re-install SS, make sure your UAC is disabled, select installer, right click and run as admin

Thanks alot for your answer! What is "my UAC" ? I heard that before, but i am not really sure what it means.

Ok, forget about the last question, found the answer myself.
