I'm using Magix music maker 2014 premium. All the instruments worked after initial install a few months back.  I haven't used this for at least 2 months.  Now none of the Vita instruments work.  When I select a vita option a message box appears showing "To use the function 'Vita solo instrument #16 an initial activation is necessary.  Would you like to activate now" and I then click 'Online' .  A graphic appears and them a message box shows there was an error -17 and to contact Magix.  Since the inital install I have upgraded to windows 10.
