Why won't my software load?

i have a fujifilm s1000fd camera. i installed long ago the software to transfer the pictures to the computer. the computer is supposed to automatically recognize the camera when i plug in the usb cable. it used to work fine but now it won't. no matter what i do. so i uninstalled the finepix viewer but when i put the software to reinstall it in the disc drive nothing happens. i have been around and around with this f****ing thing. i've attempted to contact windows, fujifilm, with no luck. in my message center i have a thing that says pcouffin device driver not installed. i've troubleshooted it with windows and they can't find a driver. no one seems to know what a pcouffin device is no one on ask yahoo, no one in the entire universe acts like they even know what i'm talking about. i've tried other software in the disc drive and nothing happens. WTF!!!!!!!!!!
