1.5 ctd with chaos factions

HI I have downloaded poxo's torrent of the game installed the translation and installed the 1.5 fix. I have played as chaos dwarves and some empire factions to turn 20 or so, but whenever I try to play as one of the four chaos factions it chrashes on start up or within turn 3. Anyone else have this problem?

okay I got it working turn 10 or so. But A daemon prince keeps spawning every 3 or so turns near my capital, I randomly entered an alliance with the chaos dwarves, and my relationships with other factions change every turn at random it seems. Is that normal?
