I purchased Music Maker Plus and a MIDI keyboard from an electronics store. I downloaded Music Maker and set up the keyboard and everything went good until I decided to activate Music Maker Plus. I clicked "Enter serial number" and entered my code, but it responded with the following message: "This serial number has already been used by another user." This is strange to me, because I have not used the code before. What should I do?
My software code has already been used, but i just entered it
