I purchased the Music Maker Plus Edition and i cant seem to find the right spot to put the key card to download the soft ware.
@Christine-Spence If you open the software you will see the Welcome screen. You can then log into your user account on the right side of the screen, just a bit above the center. There you can also enter your serial number. Alternatively this is also possible via the Help menu, if I remember correctly under the Help > Store submenu.
To download the software, you just download the free Music Maker Edition from Magix.com
