Save the video project in a new folder under My Documents then uninstall the demo version of Vegas and install the full version. You'll be asked to enter your serial number when you are installing. Your project won't be lost.

In Vegas go to help and under the pull down menu click register, it will ask for serial number there. Thats how I did it.
