Hi,

you have to reinstall the normal music maker 15, use your serial from the DVD to unlock the version. After go in the menu to the point upgrade. Now you have to use the activation code that you have recieved via email when you bought the premium version online. If you do not find the premium version activation code, lock in on magix.com online ancd check your personal service center. I am not sure of you see all your codes, but hopefully it is displayed there.

GOOD LUCK!
