Hi Al,

First things first: The version you're using is essentially two generations behind the current Music Maker. So, before we invest any further energy into troubleshooting this, you'd probably want to upgrade to Music Maker 2019 (27.x) first. You should know that you now have an option to benefit from the improvements and new features in the newest generation of Music Maker without paying for an upgrade. MAGIX has changed the complete concept for the Music Maker product line to  work like a "Freemium" model. This means there's a basic edition of the most recent Music Maker version that is available to everybody free of charge. You can download and install it from the following address:

http://dl03.magix.net/musicmaker.exe

This version will then continue to receive updates with improvements and new features, and will essentially always be up-to-date. Within this free version, you can unlock exactly the features, instruments and audio content you want through the built-in store system. As an owner of a previous, paid-for version of Music Maker (going back to Music Maker generation MX), you would be able to enter your existing serial number into this free version, which will give you access to the features and instruments that were part of your particular Music Maker version. So, this way, you get to use what you paid for, while at the same time getting to use the most recent Music Maker version that will work on the most recent Windows versions.

Check whether you're still having problems when using this new version. If so, I recommend getting in touch with MAGIX support for more detailed troubleshooting:
