This sounds as though you have plugged in the modem before you installed the drivers from the CD and it hasn't installed correctly. You need to check in device manager and see if it is listed in there and if it has a yellow mark on it. Should be listed as a globespan modem. If this is the case I think you need to right click it and uninstall it then unplug it. Then restart the laptop and run the CD again and only plug the modem in when asked to.
