Kingpin - Life of Crime (running in XP)

I'm having problems running kingpin LOC in windows xp. It runs fine on my other computer which is slightly older than the one I am running XP on. The game is jumpy, like there's not enough memory or something. I was just wondering if anyone knew of a patch or something I might need to install for this game to run properly under windows xp. Any help would be great. DrWato.
