Have you downloaded all the fixes? If so, you might want to take a look at all art related to the Warriors and remove it (just cut and paste it to another folder so you can easily restore it later). Try again without those updates and see if the game crashes. If it doesn't, it means there's an issue with one of them. It then becomes a process of elimination; restore those updates a few at a time until the game crashes again so you can pinpoint the exact file that's causing the problem. If you can pinpoint that file, it should be easier to work out a permanent solution.
If you haven't downloaded the fixes though, I'd certainly recommend doing that before anything else. See the TUP thread for more details.
