I paid for the Music maker premium upgrade, but my profile shows the Music maker Free version. The software crashed while I was using my Voucher for soundpool. I also notice that the Soundpool won't sync to the music made after reloading the software.
Go into the program settings of Music Maker and click on the button to clean up the store. This will delete the old cache of the store. This could be helpful after upgrades and updates.
Reset the program settings under the File > Settings menu
