You say that when you open device manager, it still shows the scsi card as not working correctly. Although you have already downloaded the new driver from Adaptec, it may be that Windows is not using it for the card. One suggestion would be to remove the device from device manager, close Windows, reopen Windows, and see if Windows will install it and the driver properly. Alternatively, you may be able, without removing the card, to highlight it in device manager and select properties. This will, I recall bring you to a series of dialog boxes one of which will give you the opportunity to update the driver; you then direct it to the driver you downloaded. If neither of these work, try sending a message to Nikon's technical support board. www.nikontechusa.com. You have to register, but there is no charge and registration is easy--you just pick a password. Someone told me that "Plug n' Play" is really "Plug n' Curse."
