I used to play at 1600x1024 but it made me crash a lot. With 1280x800 and low settings it doesnt crash so often, been a couple of days leaving the character with kp for hours and no problem. Something that makes me crash too is alt+enter when using the kp. You may need to give a look at the properties of the launcher and maybe with xp compatibility or disabling some stuff may make the game work better, like the game is old as ***** and our computers are new age
