MTW on windows 8.1

AFAIK Steam downloads a different Medieval_TW.exe which is very small and it's hard to notice the download process because it ends nearly immediately. This file doesn't interfere with saved games so you don't have to start a new game to see changes. Of course it was only an option not guaranteed solution (but still worth trying). To get back to the newest patch just repeat all the steps and choose "NONE".

I've tried the saved game you sent me but it doesn't crash for me. I checked the logs but not even smallest error appear so the problem is probably hardware or driver related. Try update your drivers (video card mainly). If don't know how to do it Driver Booster will help.

Thanks! Sorry for the trouble! As I am not very good (to put it mildly) at solving hardware and software problems, I'll have a geek I know try to fix it for me. If I start doing it on my own I'm afarid I'll spoil something and won't be able to mend it.

I solved the problem!!!
On the advice from a guy on the Steam forum I changed the resolution of the battle map and campaign map so that they coincided with the resolution of my computer screen and lo and behold - my game works perfectly. Although I will have to get used to things being smaller then they were. But I think this is not that important now when I can enjoy the game.
