|Have you looked in Device Manager to see if the card is installed? |
You may still need to install software in order to connect the camera to the card.
After rereading your original post I think you may have not followed the installation process correctly.
First verify if the firewire card in working properly in Device Manager. If so, uninstall any sofware you installed and reboot. Then try installing again, taking care to connect the camera when prompted to do so.
