gday

i am trying to run med2/kingdoms under vista for first time.

ive installed med2 then kingdoms except tuetonic campaign, i can do campaign stuff no problem move stacks around etc, but when it comes to battles it doesnt crash when its a low number like 3vs3, but when i do big armies on custom battle, it will for about a second after the loadbar finishes loading, go into battle, then cut back to black screen, then the loading bar comes up, fills up again and then back into battle, etc on a looping motion.

i have SS 6.1 installed with some YY improvements thingy and increase of unit size desc, thats it for mods.

i tried installing 1.05 kingdoms update but no luck so far.
ive also tried running it under administrator , and in compatibility mode for XP SP2 but still no luck.

can someone tell me what i did wrong or what i havent done that i should have?

thanks
