Last February I got Music Maker and bought the Infinity channels option. Now, the software is requesting to buy more channels option. I am using Windows 10, 64bits. Any suggestion?
You just need to be logged into your user account. If this doesn't work or the program doesn't activate your features it usually helps to log out and log back in again or to open the program settings and click on the button to clean up the store which will delete the old cache.
