I have problem with korea forgotten conflict blank screen
 

I have p4 1.3Ghz 256 mb rdram video card geforce FX 5200 win xp service pack 1 sound card on board so I dont know. directx 9.0
after installed successfully I can enter introduction movies and when the menu show up I got all white screen color and cursor is also invisible no music also I accidenttaly manage once entering the game but what I saw was black and white color with no sound or music at all, the character still can move but with invisible cursor. Do I must use regedit or patch to version 1.27. and how can I know that my version is US or UK version?
