In order to actually use the software, you have to register, then authorize, your virtual instrument. By registering, you identify yourself as the legitimate owner and thus will be sure to receive the latest news and updates for you instrument.
The Serial Number and Unlock Code are required to register & authorize your virtual instrument, so these codes are the real value of your product.
