I just purchased Music Maker Plus but I did not receive a new serial number I have checked my spam folder. I cannot activate the Plus version without the serial number.
Where did you purchased your music maker edition? Purchased editions from the in-app-store will be activated automatic and not need an additional serial number.
I purchased it from the in-app-store but it was not activated automatically. For example, it states that it comes with " 1 Complete Soundpool Bundle of your choice (a value of € 19,99) NEW! 2 preset packs + 4 software instruments of your choice." There is no Soundpool that I can choose for free and the 4 software instruments are not available/accessible. All Soundpools and software have a price tag. As far as I can determine I still have just Music maker and might as well request a refund.
On the bottom of the store you can see how many coupons you have left. When you click on BUY NOW it will auomtatic reduce the price. For more infromation read the tutorial or use the manual.
Your very helpful reply is greatly appreciated. I upgraded to Premium and have downloaded and installed everything based on your tutorial. Thanks again!
