I have a LOgitech Formula Vibration Feedback

I have a LOgitech Formula Vibration Feedback wheel, and I have some problems with it....... A few days I reinstalled my Windows (Windows Vista x32), and after that it doesn't recognize it in games. Yes I said just in games..... I can install any driver downloaded from the internet, or the driver provided with the wheel, it's not recognized. For example, NFS Underground 2 recognized the wheel before, like " Logitech Steering wheel", now it's just "Wheel", and I can't configure with wich button to turn left or right (more exactly with witch axis), it's configured to the Left and Right POV buttons. Or Test Drive Unlimited doesn't recognize the wheel at all.
Hope these details will help.
