Logitech G15 and Call of Duty 4 LCD monitor help

Hello guys;

I have been using g15 keyboard for 1.5 year and I've just started playing Call of Duty 4: Modern Warfare. This keyboard had the feature as showing the bullet damage, health remaning and etc. for compatible games. I've downloaded the latest driver and software for g15 from the logitech web site and in the web page, COD4 was on the list which showed the compatible games. I've installed the software and it matches with COD4. It also displays "profile activated Call of Duty 4" when I run the game. But during the play, the LCD monitor shows the clock as it is on windows xp where it is supposed to be showing my bullets remaining and current health. Is there any option for making it work or something else needed ? I'ld be glad if I get the solution.

Thank you.

I play Hardcore in COD4 so that wouldn't bother me at all.
