C12 works just fine but no dongle, no Halion Sonic 3

With or without a dongle C12 will properly load and play
older C11 projects with HS3 in them
(and even ‘duplicate’ the existing HS3 tracks in those projects)
but with no dongle, C12 will not ‘create a new’ HS3 track in C12.
And of course, no dongle means, no stand-a-lone HS3.
