After upgrading the software last week now I noticed to have installed Music Maker (64 bit) VERSION 29.0.0.38, but there is no reference to Premium Edition.
Is it right? Or did I change the edition of my software?
Upgrades to recent versions of MM have to be paid for! If you updated MM Premium 2020 without paying for he upgrade you now have MM Free 2021 (version 29). All the features you previously enjoyed with Premium 2020 should still be available to you, but the features newly introduced with the later version Premium edition will not.
In addition, you need to be aware that the current latest version is 30, i.e. MM 2022. If you do decide to upgrade I would suggest you do so to the latest version.
