Crash

After a slow start with this game, i tried again.
I'd install the music, i download the 1.41 fix, but the game is still unplayable.
Every campaign, after a lot of battle, it crash. I tried the same battle 3 times, and at the end of it, it crash. I tried to install again, and the problem is still there.

Even in custom battles, who i play a lot, i can't choose a fort or similar, otherwise it crash.
I have problem in some maps too. One is an ocean and i start with all the soldier underwater, mine and enemy, dead. In other maps, in the campaign too, the texture of the terrein is... horrible.

Please, this game is really good, and i wish to play more than 5 turn. There is some way to resolve them or i need to wait a new version?

1) You sure you installed everything correctly?
2) As far as siege battles, THP has a nice sticky guide.
3) Download the menu fix if you have a non-Russian version

1) Yes, i believe
2) Already read, but my problem is that i can't even select the menù. I will retry after another reinstallment maybe.
It's not the major problem still, the Campaign is the thing that most concern me.
3) Already Done
