Crash to ...?

[LordSlayer]

In the case of my game ,it stops suddenly and a message comes on a blue screen saying Windows has stopped the game due to danger of destabilisation of the system. It tends to happen during a siege.The game doesnt save so Im stuck with a bachelor Kazan Khan.

Just some ideas:

Check if you've got enough Harddisk space for the Windows Virtual memory.
Have your pc disfragmented and scanned by scanddisk.
Close as many programs as possible before strating Knights of Honor.

A blue screen? What windows do you use then? And pc configuration?

Things went from bad to worse. The game has refused to accept Disc 2 and asks for disc 1 then uninstalled KoH.
Anyhow Ive run a scandisk and I defragment frequently.
I have XP home.

Well, that's good. Reinstalling the game is always good (although you probably lost your savegames...).

Check your pc daily for spyware, too?
