@Jose-Rodriguez6561 You just need to download Music Maker Free Edition from Magix.com. After you installed it you need to log in with your user account and all your Premium Edition features should unlock automatically so you can redownload them.

If there is an error message in the program, it often helps to reset the program settings under the File > Settings menu. There is also a button to clean up the store which you can find in the program settings. It could also help to completely uninstall and reinstall Music Maker. For a complete uninstallation, which also removes all leftover files and registry entries, you can use a free tool like Revo Uninstaller.
