sidewinder gamepad usb game controller software v4 needed

Hi,
Just purchased a microsoft sidewinder gamepad usb game controller to replace my gameport version of the same gamepad, so I can use it with XP but it doesnt have the game controller software with it. Looked on the microsoft website and guess what - f*** all there - im now up the creek without a paddle until I find it cos that was the reason I purchased the usb version in the first place - because microsoft ceased releasing updates for the older sidewinder - the last version being 3.02 which is not compatable with XP. Would REALLY appreciate someone helping me out with ths one ive been searching the net for hours and im tearing my hair out here..
