I've just installed and registered Music Maker Premium 2018. The previous version on my laptop was MM Live 2016. SOME of the instruments I had in that version are now activated in the new version, but some are not (listed below). They appear under the Instruments tab, but are padlocked. When I click on the padlock, I get the main Activation dialog again; but nothing I do in there works: I've tried entering my serial number for MM2018, and for MM2016, but I just get an error telling me they (the versions of MM) are already activated and I should be able to download instruments etc. from the store.
In the Store view, the padlocked instruments also have a Purchase option. Am I supposed to buy them again? If I do, will they count against the "8 free instruments" I'm promised with MM 2018?
The instruments affected are: Bass Machine, Rock Drums, String Ensemble and World Percussion.
Thanks for any advice/help you can give.
