Greetings

I have this problem with stainless steel 6.4 , i can play custom battles without a problem, the problem comes when i play the campaign. In the campaign map i dont have any problem, but when i attack someone or when somebody attacks me the game goes to desktop and a window say me "Medieval2 stop working" and then close. I have installed and reinstalled a lot of times, and the problem remains unsolved

I have Windows 7 and Medieval 2 total war : kingdoms original from steam, other mods works without a problem except this

Thanks

Pd: Sorry for my english
