I recently purchased Music Maker Plus and after activating I installed 2 instruments, strings ensemble and power guitar and they worked fine yesterday.
Today I launched the program again and this time the two instruments were shown as locked, although I was still able to use strings ensemble but not the guitar. I attempted to activate the instruments again with my serial number but it simply says I've already activated all the content.
I'm not sure what changed from yesterday to today for it to suddenly stop working, any help would be appreciated.
(This is using windows 10, my version of MM should be the latest since I only just got it)
